Description Harald Reindl 2013-12-20 14:32:32 UTC
"ab" (Apache Benchmark) for a long time does not work on RHEL6 in case of https-sites, since it's no problem to connect to this servers from any client and "ab" from Fedora systems also works wheter ECDHE or not there must be something wrong in the RHEL package

[root@openvas:~]$ ab -c 5 -n 100 https://secure.thelounge.net/
This is ApacheBench, Version 2.3 <$Revision: 655654 $>

Comment 2 Joe Orton 2014-02-13 14:03:34 UTC
Thanks for reporting this.  The ab client in httpd 2.2.x is very rough and received significant improvements in httpd 2.4.  We currently have no plans to backport the 2.4.x changes.

If this issue is critical or in any way time sensitive, please raise a ticket
through your regular Red Hat support channels to make certain it receives the
proper attention and prioritization to assure a timely resolution.

I meant to say specifically the *SSL support* in the ab client is very rough.
