Description Alexey Proskuryakov 2016-04-14 17:16:09 PDT 
Some 12-core machines run into lots of timeouts when running 18 WebKitTestRunners (24 virtual cores * 0.75, which is a quotient for WebKit2).

I'm not really sure why it's a problem with GuardMalloc while it's not a problem with regular builds. We definitely have enough RAM for all.

But it seems like bringing the number further down to 12 doesn't reduce performance anyway.
