At times it can be dog slow from emulated disks, but once the OS is cached into memory it actually fairs quite well, considering just how long Xen has been ported to OpenSolaris. Extra sockets or cores really doesn't help Windows under xVM, it's not optimized to benefit from SMP (Specifically to Xen). Isolating one of my cores was enough to get it to run right, but due to my usage of zfs and the amount of ram I have, it can easily crawl. The performance is only better by a smudge with Xen 3.1 on Linux, not really noticable. With a real FB driver, animations and videos still won't play that well, they don't do too well in VMware considering, but at least then will most of the glitches that we see day to day will be less obvious. In due time, hopefully it can be marginally comparable to VMware on the same hardware, but for now, you can't get any real work done with HVM domains.
