[HTCondor-devel] How to speed up HTCondor 33% without really trying

[Greg Thain <gthain@xxxxxxxxxxx>]

I finally got my desktop upgraded from CentOS 6 to Ubuntu 18. Amount 
other things, this means going from gcc 4.4 (last touched around 2012) 
to gcc 7.3 (last touched early 2018).


As a simple benchmark, I ran condor_history on a large history file, 
many times, and took the fastest result, on CentOS 6, and then on 
condor_history rebuilt from sources on Ubuntu:

CentOS 6: user cpu: 13.833 seconds

Ubuntu18:user cpu:Â 9.316 seconds


Found these numbers interesting.
