Looking at <http://build.webkit.org/builders/Windows%20Debug%20%28WebKit2%20Tests%29/builds/633> vs. <http://build.webkit.org/builders/SnowLeopard%20Intel%20Release%20%28WebKit2%20Tests%29/builds/1624>:
jscore-test took 267 seconds on Windows vs. 18 seconds on SnowLeopard
layout-test took 1711 seconds on Windows vs. 601 seconds on SnowLeopard
That adds up to an extra 22.5 minutes on Windows, which explains most of the difference between the two.
Perhaps the biggest issue is that Windows is using Debug builds, while Mac is using Release? Maybe we should change the Windows WebKit2 bot to use Release builds.
