Hello,
I would like to share my experience with rendering the same scene (Benchwell 1.7 "sculpture.mxs") on different platforms:

On an overclocked (2,40GHz/2.76GHz) Intel Q6600 Core2Quad
8 GB RAM
# Ubuntu 9.04 64bit -18m 3s
# Windows Vista Ultimate 64bit -20m 14s
# Windows 7 Ultimate 64bit -21m 26s

Not much difference but Windows 7 is slower...

I tried the same test on another slower computer Intel xw4600 E8500 (3.16GHz) with 3.48 GB RAM
# Ubuntu 9.04 64bit -42m 11s
# Windows XP 32bit -32m 12s!!!

On a 4600 a 64bit Ubuntu is 10 min slower than 32bit Windows XP!

How is this possible? I am tempted to install XP on my main computer but am unable to do it right now and I really need the 8 GB RAM (that you can't use in 32bit)

Cheers,
Jakob Ryngen

Wow really interisting find. Maybe it's because of different services and program running in the background?
And Maxwells optimisations maybe too.

A friend of mine uses a fresh installed plattform for productivity work only. He has his 2D and 3D programs installed. Nothing more. Plus he loads a restore point from time to time to keep his working partition fresh.

On his other Partition he has all his other programs. So if he want to test a program he installs it there. I will do the same if Win7 comes out maybe. I even considered a downgrade from vista x64 to xp x64.

Hello Jakob,

That is interesting, I did some tests like yours and found this:

viewtopic.php?f=16&t=32056

However, I did NOT test the 32-bit version of windows.

Are you running/installed something else on ubuntu other than Maxwell?

yeah I had some stuff that rendered faster on 32 bit. however since scenes are getting more and more heavy, 32 bit is obsolete...

Nope, I only used Ubunto for Maxwell rendering as I thought it would be FASTER in 64 bit. Big surprice!
