- run-perf.pl initial commit

[Sashan]

script is able to run perf tools and collect data in .markdown format on windows, unix (BSD), macos and linux. It is perl variant of the run-perl.sh (same tool implemented in bash). Unlike bash variant this version requires tools to be compiled first.

There seems to be no easy way to run bash script on windows. the perl seems to be better bet.

The list of force pushed changes since initial commit:

• rwlocks tool returns two numbers, the first is stat for write lock, second is read lock stats, I got it wrong first
• rwlocks tool when running for single thread returns NaN for write lock stats, the NaN result is handled now
• tool reports a test name and openssl version it is currently testing

new revision also supports stuff from @andrewkdinh which got mergerd recently (#4)

Could you please drop the commits from the Andrew's PR? They are already merged.

[Sashan]

I think I will start with fresh pull-request. there must be something wrong with my clone
will figure it out later.

poor git driving -- again.

[Sashan]

Now the PR is in shape I'd like to merge in.
thanks for patience.

done. new version

• does not need tweaks to post-process output of pkeyread and evp_setpeer, because of - terse output must show number only #8)
• needs to make sure the number of threads to run is always the last argument (because of this change makes handshake and x509storeissuer command #12)

Another option would be to just skip rwlock measurements for now. IMO they are not particularly useful anyway as they just measure the speed of something that is not going to change much. In this sense the benchmark is completely synthetic and outside of OpenSSL realm. It was useful for comparing the rwlock performance with rcu locks but not useful that much anymore.
