Hi, I am using curl-loader to load test a web application. While testing I found that curl-loader logs an extra time-out error message intermittently in the .log file. This is what I have done so far: 1. I have a list of 13 urls in the conf file each with a time out of 1000 milli seconds. 2. I ran curl-loader as curl-loader -f <conf file> -e -v with following settings in the conf file CLIENTS_NUM_MAX=500 CLIENTS_NUM_START=50 CLIENTS_RAMPUP_INC=100 ..... CYCLES_NUM= 1 URLS_NUM= 13 3. And here's a cut from the actual .log file: 2143 0 0 134 !! OK 200 2424 0 1 134 !! OK 200 2511 0 2 134 !! OK 200 2594 0 3 134 !! OK 200 2682 0 4 134 !! OK 200 2829 0 5 134 !! OK 200 3115 0 6 134 !!

This happens very few times (2-3 instances) and happens only when I run the test with clients > 500. Could any one please let me know what can be the reason for this?

Hi Robert, Thanks. This is the version of curl-loader that I'm using: curl-loader-0.51 Can libcurl library be installed separately with https support enabled? And I'm not facing this issue when I send a https request through command line curl tool. Thanks. Pradhikshaa |

Which version of curl-loader you are using?

Please, look at your server-side. From this point see, that your server/servers are good with the load.

Hi Dave, I've actually tune it accordingly from this website http://curl-loader.sourceforge.net/doc/faq.html#big-load ulimit -n 100000 sysctl -w tcp_tw_recycle=1 sysctl -w net.ipv4.tcp_tw_recycle=1 sysctl -w net.ipv4.tcp_tw_reuse=1 sysctl -w fs.file-max=100000 sysctl -w net.ipv4.conf.all.arp_filter=0 sysctl -w net.ipv4.conf.all.rp_filter=0 sysctl -w net.ipv4.conf.eth2.rp_filter=0 sysctl -w net.core.rmem_max=16777216 sysctl -w net.core.wmem_max=16777216 sysctl -w net.ipv4.tcp_rmem="4096 87380 16777216" sysctl -w net.ipv4.tcp_wmem="4096 87380 16777216" sysctl -w net.ipv4.tcp_mem="16777216 16777216 16777216" echo 1024000 > /proc/sys/net/ipv4/neigh/default/gc_thresh1 echo 1024000 > /proc/sys/net/ipv4/neigh/default/gc_thresh2 echo 1024000 > /proc/sys/net/ipv4/neigh/default/gc_thresh3 I manage to get the link usage to around 800mbps but after 5 minutes, the link usage drops to around 200mbps.

There are several examples of how to use it in curl-loader/conf-examples/ , e.g. bax-login-logoff-noncycling.conf and multipart-formdata-post.conf, etc Perhaps you'd like to fetch a URL by GET and afterwards to make a POST. at the same URL. You are placing URL="" to the POST-part to indicate, that you start a new URL section for POST-ing a form and URL_USE_CURRENT= 1 to indicate that you are using the URL resulting from the very previous GET (it may be some redirections at server). For example see in the files, e.g. # GET-part URL= http://10.30.6.42:8888/vax/root/Admin URL_SHORT_NAME="Login-GET" REQUEST_TYPE=GET TIMER_URL_COMPLETION = 4000 TIMER_AFTER_URL_SLEEP =0 # POST-part URL="" URL_SHORT_NAME="Login-POST" URL_USE_CURRENT= 1 REQUEST_TYPE=POST etc , etc Header Expect of HTTP 1.1 makes sense to place to the POST URL section, whereas it is up to you to decide the place of HTTP_REFERRER, or it can be sent in both HTTP requests. You can start with a single client and always use some sniffer like Wireshark to monitor your progress and actual headers sent. > Thanks in advance for any help! > Take care.

Hi again, I'm trying to set the HTTP_REFERER header in my conf file using a HEADER line as below: URL=https://myurl/submissions/createupload URL_SHORT_NAME="Upload-POST" HEADER="Expect: " HEADER="HTTP_REFERER: https://myurl/account/login" REQUEST_TYPE=POST MULTIPART_FORM_DATA="submission[uploaded_content]=@./fixtures/dummyfile.txt" And it doesn't seem to be working, which is to say my app is checking for the header and its not there. I know curl has a command line option to set the referer. Is there, perhaps, a way of passing this into curl-loader? Or perhaps my syntax is just wrong? Thanks in advance for any help!

Hi, I just signed up to the list to see if I could find out how to install onto OSX, but I see that question has recently been asked (by Götz). If it really is exclusively Linux, it would be helpful if the Freshmeat page didn't state POSIX as one of the supported operating systems - I wasted an hour or so messing with the Makefile. I've got it installed in an Ubuntu VM, now, but I would have preferred not to have had to do so.

Hi folks, version 0.53, March 11 2011, svn 584 * Updated to the latest libcurl, libevent and c-ares; * Fixed compilation issue at Fedora-8 with extern declaration of pread in parse_conf.c; * Added patch providing URL randomization. Thanks to Pranav Desai <pra...@gm...> for this patch. It was also fixed patching of libevent to increased number of simultaneous connections from 4K to 128K, but fill you free to increased it even more. It was added clarifications in README regarding tuning of linux ARP-cache for heavy load with thousands of IP-addresses. Take care. Shabbat shalom.

Hi, I’d like to try curl-loader but it fails building on my Mac OS X system. First, in fdsetsize <bits/types.h> is included - my system doesn't have this. I tried another one. Second, "conf.h:27:51: error: linux/limits.h: No such file or directory" – obviously my system doesn’t offer a "linux" dir Has anyone ever successfully built curl-loader for a UNIX system? Perhaps even Mac OS X? Regards Götz |
