Hello
I want to get high https stream with curl loader, but the Https throughput
is about 800kbps between two PC, Http throughput can reach 950Mbps in that 2
pcs, I do know if some have experience like this, and get a high https
throughput with curl-loader, Thanks for any supports and help!!

Dear Robert
Thanks a lot for your replay,
Here are some answer about your questions
What happens if you try HTTP? Does it impact throughput?
It is normal and perfect if I test with HTTP, The throughput can reach to
950Mbps.
Which tools you are using to measure throughput?
There are 2 ways I used,
1 check the log summary form cur-loader like this"
Ti:5261372B/s,To:18375B/s"
2 check real time traffic speed on switch with connected test PC and HTTP
server
What happens, if you try just to ftp some large file between the machines?
NO test
What about CPU usage at both client and server?
Both they are busy, about 80%
Which HTTP server is in use?
Apache/2.2.21
Have you looked into logs of curl-loader and your web-server?
Checked log, not find abnormal issue.
Today, I used Loadrunner11 to simulate https traffic with same environments
(same apache server) , it can reach to 110Mpbs. But still only get 800kbps
with cur-loader.
Best Regards,
CK

Hi CK Zhang, Now it clear what happens. curl-loader: - establishes TCP connections; - makes expensive TLS/SSL handshake - fetches the file. After fetching file, curl-loader closes the TCP-connection. Next cycle it establishes the TCP-connection and makes the expensive TLS/SSL handshake again, and fetches the file. To achieve high throughput libcurl needs to be configured to re-use the established TCP connection and TLS/SSL for the next file transfer and not to re-establish it every cycle. I suggest you to look in curl (libcurl) options and I will also be doing that. Thanks for your reporting.

Thanks a lot for your help!! Best Regards, CK #8042 -----Original Message----- From: Robert Iakobashvili [mailto:cor...@gm...] Sent: Wednesday, October 12, 2011 4:52 PM To: curl-loader-devel Subject: Re: HTTPS throughput too low Hi CK Zhang, Now it clear what happens. curl-loader: - establishes TCP connections; - makes expensive TLS/SSL handshake - fetches the file. After fetching file, curl-loader closes the TCP-connection. Next cycle it establishes the TCP-connection and makes the expensive TLS/SSL handshake again, and fetches the file. To achieve high throughput libcurl needs to be configured to re-use the established TCP connection and TLS/SSL for the next file transfer and not to re-establish it every cycle. I suggest you to look in curl (libcurl) options and I will also be doing that. Thanks for your reporting.

hi, Robert: May be my problem is another issue, I use FRESH_CONNECT in my test plan(for I have to simulate huge of person login in a short peroid of time). when CLIENT_NUM reach to 300, the cpu consumption in client end exhuasted very much(client cpu 8*Intel(R) Xeon(R) CPU E31230 @ 3.20GHz), client idle below to 30%, I change the https to http, Still the total QPS to server only 1100, AND the server has litter pressure. I also found there many TIME_WAIT socket state in my nginx server, It reach 68546(Ii use multi machine as client), does this have any affect? my question is FRESH_CONNECT operation is an very cpu-comsumption operation? Do you have any suggestion?

Dear Wei Guo, Yes, your considerations are correct. You can increased descriptor limits and others as explained here: http://curl-loader.sourceforge.net/doc/faq.html#big-load Still, you will come to some openssl related limitations. You can try to build libcurl against some other TLS/SSL library (curl site explains how to do that) and to patch curl-loader's Makefile and some places in loader.c Kind regards, Robert On Tue, Aug 28, 2012 at 5:25 AM, wei guo <wei...@gm...> wrote: > hi, Robert: > May be my problem is another issue, I use FRESH_CONNECT in my test plan(for > I have to simulate huge of person login in a short peroid of time). when > CLIENT_NUM reach to 300, the cpu consumption in client end exhuasted very > much(client cpu 8*Intel(R) Xeon(R) CPU E31230 @ 3.20GHz), client idle below > to 30%, I change the https to http, Still the total QPS to server only 1100, > AND the server has litter pressure. > > I also found there many TIME_WAIT socket state in my nginx server, It reach > 68546(Ii use multi machine as client), does this have any affect? > > my question is FRESH_CONNECT operation is an very cpu-comsumption operation? > Do you have any suggestion? > > > > On Mon, Aug 27, 2012 at 12:09 PM, Robert Iakobashvili <cor...@gm...> > wrote: >> >> Hi wei guo, >> >> It's a libcurl issue when built with openssl. >> >> More throughput could be delivered, probably, if to build libcurl >> against some another TLS/SSL library. >> >> You can try it. >> >> Regards, >> Robert Iakobashvili, Ph.D. >> >> Home: http://www.ghotit.com >> Blog: http://www.ghotit.com/category/ghotit-blogs/ >> Twitter: http://twitter.com/ghotit >> Facebook: http://facebook.com/ghotit >> ...................................................................... >> Ghotit Dyslexia >> Assistive technology that understands you >> ...................................................................... >> >> >> On Mon, Aug 27, 2012 at 5:38 AM, wei guo <wei...@gm...> wrote: >> > hi,all: >> > do you have any conclusion for this issue？ I ran into the same problem, >> > I'll >> > look for answers for this. >> > >> > On Wed, Oct 12, 2011 at 4:51 PM, Robert Iakobashvili >> > <cor...@gm...> >> > wrote: >> >> >> >> Hi CK Zhang, >> >> >> >> Now it clear what happens. >> >> >> >> curl-loader: >> >> - establishes TCP connections; >> >> - makes expensive TLS/SSL handshake >> >> - fetches the file. >> >> >> >> After fetching file, curl-loader closes the TCP-connection. >> >> >> >> Next cycle it establishes the TCP-connection and makes the expensive >> >> TLS/SSL handshake again, >> >> and fetches the file. >> >> >> >> To achieve high throughput libcurl needs to be configured to re-use >> >> the established >> >> TCP connection and TLS/SSL for the next file transfer and not to >> >> re-establish it every cycle. >> >> >> >> I suggest you to look in curl (libcurl) options and I will also be >> >> doing >> >> that. >> >> >> >> Thanks for your reporting. >> >> >> >> On Wed, Oct 12, 2011 at 2:59 AM, CK Zhang <ck...@fo...> wrote: >> >> > >> >> > Attached logs, and output from console >> >> > >> >> > ============ loading batch is: Apach >> >> > ====================================== >> >> > >> >> > >> >> > ---------------------------------------------------------------------------- >> >> > ---- >> >> > Interval stats (latest:3 sec, clients:100, CAPS-curr:60): >> >> > H/F >> >> > >> >> > >> >> > Req:0,1xx:0,2xx:0,3xx:0,4xx:0,5xx:0,Err:0,T-Err:0,D:0ms,D-2xx:0ms,Ti:0B/s,To >> >> > :0B/s >> >> > H/F/S >> >> > >> >> > >> >> > Req:200,1xx:0,2xx:201,3xx:0,4xx:0,5xx:0,Err:0,T-Err:0,D:553ms,D-2xx:553ms,Ti >> >> > :6854220B/s,To:18800B/s >> >> > >> >> > >> >> > ---------------------------------------------------------------------------- >> >> > ---- >> >> > Summary stats (runs:48 secs, CAPS-average:60): >> >> > H/F >> >> > >> >> > >> >> > Req:0,1xx:0,2xx:0,3xx:0,4xx:0,5xx:0,Err:0,T-Err:0,D:0ms,D-2xx:0ms,Ti:0B/s,To >> >> > :0B/s >> >> > H/F/S >> >> > >> >> > >> >> > Req:2878,1xx:0,2xx:2873,3xx:0,4xx:0,5xx:0,Err:0,T-Err:0,D:614ms,D-2xx:614ms, >> >> > Ti:6087722B/s,To:17182B/s >> >> > >> >> > >> >> > ============================================================================ >> >> > ===== >> >> > Manual: clients:max[100],curr[100].
