I've experienced a substantial slowdown in VMware since bumping forwards from -STABLE on my workstation. As I recently commented on -emulation, I've also been experiencing 30-40 second hangs of the system during VMware startup and occasional serious slowdown while running, which may be related to the fairly intensive VM activity for page wiring and the like, or possible poor interaction with the ATA driver. I also get messages on the order of the following: swap_pager: indefinite wait buffer: device: ad0s1b, blkno: 2696, size: 4096 And have heard that others have started getting them also, although don't have confirmation of that. It may be that things need retuning a bit in -CURRENT, or that we need to wait for SMPng to do some pushdown of locks.
