A letter to PC pro
You have miss stated that the apple mac pro is the fastest PC in the UK in your article here http://www.pcpro.co.uk/news/95175/apple-mac-pro-is-crowned-the-fastest-pc-in-the-uk.html
This is complete hogwash, and by that I mean that you really haven’t looked around for fast computers.
The mac pro is cheap but fast prettified nonsense. It looks nice but heres the kicker, the OS and kernel are incredibly slow in comparison to other OS’s and moreover the Xeon is STILL being out performed by opterons.
The Sun ultra40 workstation which you can find here http://www.sun.com/desktop/workstation/ultra40/
is most certainly the fastest PC in the UK, especially when using Solaris. This essentially rests on the solaris kernels ability to actually make proper use of symmetric multi processors as they’ve had a good 25 years to develop that part of the operating system as it has been their core competency. The Xnu or Xinu or Mach kernel as is in OSX is nothing but a mixed up muddled up BSD/NeXT kernel which is completely incapable of exploiting non determinism within a multi processor setup. Moreover the governance of the SMP in the Xnu kernel is disproportionate to the performance gain.
I have personally seen a sun workstation build a linux kernel in under 10 minutes, generally around 3-4 and wine in around 23 minutes, apple couldn’t even hope to reach that kind of optimised SMP in their operating system and that was all done in LINUX!!! In solaris the performance gains are even more incredible as the solaris kernel is the most advanced kernel in the world.
I therefore suggest that you either haven’t tested this workstation at its highest spec, or have used benchmark tools which are wildly biased against the AMD opteron processor.
Its true what Simon Phipps said to me “Sun never get favourable reviews, even when their products out perform the competition”
