I'm using the 3188 trial and I noticed that even with as little as 384MB allocated to a WinXP installation that the memory usage causes my Macbook to swap quite a bit. I can understand XP swapping with so little memory but i'm seeing Mac OS pageouts before the XP desktop appears. Is there something i'm doing wrong? I read through the forums that Parallels itself needs around 96MB... but with 1GB free memory I wouldn't expect to see any pageouts with a tiny 384MB allocation for XP. As a side note... Life seems better with the paging file disabled on XP. At least I know when i'm reaching the end of my rope within the VM. I'd rather get a warning that i'm out of memory in XP than thrash my hard disk writing the XP pagefile.
