Great findings Arwyn,

One thing perhaps that you may consider is to use the WS API, where clientToolBox has a CLI. You can perform the three commands you list using the local CLI with a single WS/WS CLI command if using a CSR:
./ejbcaClientToolBox.sh EjbcaWsRaCli certreq
Or multiple commands as well if issuing keystores (pkcs12), with your "own" WS client you can do other things as well.
The WS API may be faster if it's the CLI remote EJB commands that are slower in newer WildFly.

Cheers,
Tomas

Thanks Tomas,

I currently do not believe the slow down is caused by the EJBCA or cesecore server side.

I turned on trace logging for only ejbca and cesecore loggers on the server side. All of these log messages appeared within 0.75 seconds of each other for EJBCA6 and within 0.85 seconds of each other for EJBCA7. This means I don’t think there has been a significant change to the server side performance of EJBCA or cesecore logic.

When running a bin/ejbca.sh command I have observed the client ejbca.sh JVM startup time to be very similar in both versions of EJBCA, at around 1 second. In the case of EJBCA 6, the EJBCA and cesecore log messages show up ~ 0.5 seconds after the JVM has fully started up. In the case of EJBCA 7 the EJBCA and cesecore log messages show up ~ 1.7 seconds after the JVM has started up. This makes me think that either the client is slower by ~1.2 seconds in the new version, or there is some slow down in wildfly and the EJBRemoteInvocation.

This gives the total time for one ejbca.sh command to go from ~2.25 seconds in EJBCA 6 to ~3.55, with most of this difference coming from the change in the client. (I believe changing the logging levels have had a slight effect on the performance, which is why these values are different to my original comment).

Over a typical certificate renewal I would call the ejbca.sh command three separate times.

The three commands I run would be

bin/ejbca.sh ra setendentitystatus --username " user.name" -S 10

bin/ejbca.sh ra setpwd --username "user.name” --password “password”

bin/ejbca.sh createcert --username “user.name” –password “password” -c “/tmp/tmp_csr” -f “/opt/ejbca/p12/pem/user.name.pem”

As the server typically takes less than a second to respond, the change to the client performance is resulting in this process taking between 1.5 and 2 times longer than previously.

I’ve been having some trouble running the stress test tool but I will try to get results from that to confirm the client is the issue. You mention that the stress test tool is able to run without having to restart the JVM. This leads me to thinking that it may be possible to follow the same pattern when running my certificate renewal. Is it possible to run multiple bin/ejbca.sh commands without restarting the JVM? If the JVM is reused, it may mean that the slow down in the client that I have observed would not have such a large effect over a typical workflow.

Regards,

Arwyn

Can you rule out that it is anything on the client side that is slow?

For performance measurement of EJBCA itself, we typically run a "clientToolBox stress" which is a nice stress test tool that runs multiple threads in a single client JVM, avoiding any JVM loading issues, and showing certificate issuance speed. You can test single threaded performance (measure latency) and multi-threaded performance measuring throughput.

This tool has been available since EJBCA 4 and can be used throughout the times.

Thousands of CAs sounds like a quite special use case. Not a very normal use case.

For sure EJBCA 7 is running in production issuing hundreds of certificates per second, from dozens of CAs, but I haven't been digging around with thousands of CAs yet personally.

Hi Tomas,

I have now enabled trace logging on the client side.

I have seen the longest message is the following, which takes approximately 0.6 seconds. I have been unable to find a similar log message in the log of the EJBCA 6 client.

TRACE [SecurityProviderSaslClientFactory] - Created SaslClient for mechanism JBOSS-LOCAL-USER, using Provider WildFlyElytron and protocol remote

The above log message always occurs between the following two DEBUG log messages, which seems to be where most of the slow down is seen.

2021-11-08 14:16:52,865 DEBUG [DiscoveryEJBClientInterceptor] - DiscoveryEJBClientInterceptor: calling executeDiscovery(locator = StatelessEJBLocator for "ejbca/cesecore-ejb/GlobalConfigurationSessionBean", view is interface org.cesecore.configuration.GlobalConfigurationSessionRemote, affinity is None, weak affinity = None)

2021-11-08 14:16:53,298 DEBUG [DelegatingBasicLogger] - Received MODULE_AVAILABLE(8) message from node <host> for module ejbca/certstore

Another log message that seems to be taking a while in the client log is the following. This takes approximately 0.3 seconds the first time it shows up, but is much faster on subsequent appearances inside the same ejbca.sh call.

2021-11-10 09:11:56,605 TRACE [AuthenticationContextConfigurationClient] - getAuthenticationConfiguration uri=http-remoting://localhost:4447, protocolDefaultPort=-1, abstractType=ejb, abstractTypeAuthority=jboss, MatchRule=[abstractType=ejb,abstractTypeAuthority=jboss,host=localhost,port=4447], AuthenticationConfiguration=[AuthenticationConfiguration:principal=anonymous,set-host=localhost,set-protocol=http-remoting,set-port=4447,providers-supplier=org.wildfly.security.provider.util.ProviderServiceLoaderSupplier@93e09b04,mechanism-properties={javax.security.sasl.policy.noanonymous=false, javax.security.sasl.policy.noplaintext=true, wildfly.sasl.local-user.quiet-auth=true}]

I have been doing this upgrade testing on my system where I have 500 CAs configured. My system is only used for testing, as the production system would be at EJBCA 6 currently. I would expect there to be a few thousand CAs on the production system.

Regards,

Arwyn

Have you enabled debug logging? That should show clearly if there is anything in EJBCA that takes time.

Question: do you have 500 CAs configured? Is this a production use case?

Cheers,

Tomas

Thanks Tomas,

I think my previous message regarding the client may have been incorrect. In the EJBCA 7 case I’m getting a io.undertow.request log in the server log approximately 1s after calling ejbca.sh, which is when I think the client JVM has started up. However  there is then an approximately 1 second gap before the first cesecore log shows up (org.cesecore.configuration.GlobalConfigurationSessionBean). During this time the server does not seem to be doing anything, but the client is.

In the EJBCA 6 case the first server log appears approximately 1 second after the ejbca.sh command is called, but it then takes only ~0.3 seconds for the cesecore log to show up. So it looks like the client is now taking ~2 seconds to connect after the upgrade, vs the old client taking ~1.2 seconds. You mention a slow client has been observed before, is there a way of finding out the cause and finding a way to speed up the client startup?

I have now checked all of the DB indexes in the doc/sql-scripts/create-index-ejbca.sql script. After putting all indexes in place it does not seem to have had an effect on the total time.

I have tested this and observed the slow down for up to about 500 CAs.

Arwyn

Sounds like you are missing a database index. Check the recommended database indexes.

Do you have many CAs, and/or CA certificates?

Thank you for the response. Currently we believe the issue is server side. I have compared the time between the ejbca.sh cli command being called and messages appearing in the server.log. This time was the same for both EJBCA 6 and EJBCA 7.

I have tried profiling the older version of EJBCA 6 to compare it to the results we found for EJBCA 7. The getCAInternal function was taking approximately 0.05 seconds on the old version, approximately 10 times quicker than in EJBCA 7. I could not find getCertificateProfile when running EJBCA 6. These are the only functions from the ejbca or cesecore packages that seemed to be taking a long time in EJBCA 7, and as there is such a large difference in these functions after the upgrade we think this could be the cause of the issues.

Has there been any changes to the internal EJBCA caching from the upgrade? Is there any specific options that mean EJBCA does not cache certificates anymore?

Regards,

Arwyn

*External Message* - Use caution before opening links or attachments

If anything, the performance of EJBCA should be better not worse after an upgrade. Did you check recommended indexes to add new database indexes that should be there. There are some new ones that we recommend. See doc/sql-scripts for the recommended indexes. As you already checked slow queries though, it may or may not help anything.

If it just startup of the cli command that takes time, or does every request take time if you for example run a stress test? I.e. identify if its the client or server that has slowdown. You can check the server.log to see when a request come in and how long it takes to process.

We have seen cases where for various reasons the startup/init time of java on the client side takes time, i.e. not EJBCA that is slow but the start-up of the JVM for the CLI client side process.

Regards,

Tomas

Hi,

We are currently in the process of upgrading the version of EJBCA we use and have noticed a significant decrease in performance. Our previous installation used EJBCA version 6.3.1.1, jboss version 7.1.1, and opendk 7. We have tried to upgrade to EJBCA version 7.4.3.2, wildfly version 18.0.1, and openjdk 8.

We have noticed that ejbca.sh commands take approximately twice as long after the upgrade, for example ./ejbca.sh ra setendentitystatus went from ~1.5 seconds before the upgrade to ~3 seconds after the upgrade, and .ejbca.sh createcert went from ~2 seconds to ~4 seconds.

We have tried some of the options in the PerformanceTuning (https://doc.primekey.com/ejbca743/ejbca-installation/application-servers/wildfly-18-jboss-eap-7-3#WildFly18/JBossEAP7.3-PerformanceTuning<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Furldefense.com%2Fv3%2F__https%3A%2Fnam11.safelinks.protection.outlook.com%2F%3Furl%3Dhttps*3A*2F*2Furldefense.com*2Fv3*2F__https*3A*2Fnam11.safelinks.protection.outlook.com*2F*3Furl*3Dhttps*3A*2F*2Furldefense.com*2Fv3*2F__https*3A*2Fnam11.safelinks.protection.outlook.com*2F*3Furl*3Dhttps*3A*2F*2Furldefense.com*2Fv3*2F__https*3A*2Fnam11.safelinks.protection.outlook.com*2F*3Furl*3Dhttps*3A*2F*2Fdoc.primekey.com*2Fejbca743*2Fejbca-installation*2Fapplication-servers*2Fwildfly-18-jboss-eap-7-3*23WildFly18*2FJBossEAP7.3-PerformanceTuning*26data*3D04*7C01*7Ctomas.gustavsson*40primekey.com*7Cb5562e5e7ab14034f90808d99fba0f08*7Cc9ed4b459f70418aaa58f04c80848ca9*7C0*7C0*7C637716444467209936*7CUnknown*7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0*3D*7C3000*26sdata*3DeKHxGCeaet56ecbgaoxt6WzH4*2F*2FLzB9Zw7T*2Ft5eYBEQ*3D*26reserved*3D0__*3BJSUlJSUlJSUlJSUlJSUlJSUlJSUlJSUlJQ!!In4Qlw!6ZvD7OSOz-ZOVXXibdUGr8TXgIluCtaXVSPBS0iknh_KKTh-trtTeYreMBdyiA9e9GI*24*26data*3D04*7C01*7Ctomas.gustavsson*40primekey.com*7Cd1ea972107fb4d26293a08d9a0882a3e*7Cc9ed4b459f70418aaa58f04c80848ca9*7C0*7C0*7C637717328989428655*7CUnknown*7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0*3D*7C1000*26sdata*3DBEAkcfNI7HxZ5iFmsFpWTfvJRTVqjZAtgUL1TF2nlvI*3D*26reserved*3D0__*3BJSUlJSUlJSUlJSoqKioqKioqKiUlKioqKioqKioqKioqJSUqKioqJSUlJSUlJSUlJSUlJSUlJSU!!In4Qlw!_2cNsYkEMpPutSXEorm2ptooFtWhc5Jm_SZI6aA_0-guiyQ8dkI9smRCjrBx1rbvaWU*24*26data*3D04*7C01*7Ctomas.gustavsson*40primekey.com*7Ce351c5fc7ff64a58a4e408d9a2db3098*7Cc9ed4b459f70418aaa58f04c80848ca9*7C0*7C0*7C637719884629212861*7CUnknown*7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0*3D*7C1000*26sdata*3DzQOUT2OHUnYk3*2FkG33oixtRpI*2BXE6*2Bjxw5rYv32X8O4*3D*26reserved*3D0__*3BJSUlJSUlJSUlJSoqKioqKioqKioqKioqKioqKioqKioqKioqKioqKioqKioqKioqKioqKiolJSoqKioqKioqKioqKiUlKiUlJSUlJSUlJSUlJSUlJSUlJSUl!!In4Qlw!8-KVx3UAT0IxCIX12v4XCzVWZ8GHzkq_jDBw5LrqWPF1ZcRlbItU0ZJmT4tM4IUl8eU*24%26data%3D04*7C01*7Ctomas.gustavsson*40primekey.com*7C857053cb62f54686422308d9a4f1adc5*7Cc9ed4b459f7041&data=04%7C01%7Ctomas.gustavsson%40primekey.com%7C99b31a6ee64c405a7c0608d9a521b651%7Cc9ed4b459f70418aaa58f04c80848ca9%7C0%7C0%7C637722386517939677%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=rG1z4ECGieWdljg3Fre5E%2F9oPHaNtpLwSxuxswUCTzA%3D&reserved=0>) section of the documentation, which has had no significant effect on the performance.

We have tried profiling the EJBCA process, but have not yet found anything that is obviously causing the performance issues. Currently we have seen that both Lorg/cesecore/certificates/certificateprofile/CertificateProfileSessionBean:::getCertificateProfile and Lorg/cesecore/certificates/ca/CaSessionBean:::getCAInternal take approximately 0.5 seconds each during a setendentitystatus run. These seem to be taking a long time but we're not sure if they are the actual cause of the performance issues.

We currently don't believe the MySQL DB is the cause of the performance issues as there were no entries in the Slow Query Log for any time greater than 50ms.

Does anyone have any suggestions on how we could improve the performance of our installation, or how we would find the source of the performance issues?

Kind Regards,

Arwyn
