It looks like a single core on a T1000 is much less powerful than a single core in a Dell 2850, so this might account for some of the difference.
That is precisely the case. A quote Obviously, the UltraSparc T1 will perform quite poorly on workloads that require single-threaded performance. For those types of non-multithreaded workloads, Sun will rely for the time being on its Opteron-powered Galaxy server line. In 2008, however, Sun plans to release a new design codenamed "Rock" with better single-threaded performance. taken from http://arstechnica.com/news.ars/post/20051114-5569.html You can find a bit more info here: http://arstechnica.com/news.ars/post/20051116-5584.htm This Sun hardware is built /specifically/ for running /highly/ multithreaded code, it has always sucked royally at single-threaded performance, this was very much a design decision.
