Installed a fresh VM with a Windows XP 64 bit ISO, sp2 already
applied. VM has 512 MB ram, and the only package I installed after the
OS was cygwin. Issue presents in this environment as soon as Firefox
connects/starts. Page Faults Delta over 5,000 minimum anytime I'm
doing anything in Firefox, including typing this message, usually over
10,000.
I just fired up a 64-bit Ubuntu VM I had laying around, installed
firefox, and tunneled it to cygwin64/X on my win7-64 machine. X isn't
even visible in the task manager when I sort descending by PF delta,
CPU, or memory. This in spite of having half a dozen tabs with content
(including ads, an html5 game, and a youtube video playing).
Opening a couple dozen more empty tabs brought PFdelta up to the ~7k
range, but the rate dropped back to ~0 as soon as the dust settled.
Typing remains fully responsive, and I'm officially out of ideas.
