Re: 30% random performance in 0.95+
Yep, I will start that tonight or tomorrow morning when 8755 will be
done. Since it will take at least 5 days I will most probably order a
new server in the meantime to not block the other performances
investigations ;)

So don't expect results before wednesday....

Another option is to run tests every 50 commits to reduce the number
of tests and get an idea faster, but the range will be bigger so will
be harder to spot the modification which improved the read.
