hyperthreading

[moyesboy]

Its probably well known among everyone on here, but I just increased the performance of solidworks a lot on one of our PCs by disabling hyperthreading on the processor.
Previously SW was limited to 50% of CPU - not necessary as this particualr PC does nothing but solidworks.

You are correct.

Have you read faq731-376 to make the best use of these Forums?

Apparently, hyperthreading with the Intel i7 CPUs is acceptable.

I notice CPU seems to be limited to 25% on my i5 750 PC.
i.e. SW seems to be running on only one of my 4 CPU cores.
I can disable multiple cores in the bios - I can set it to have 1,2, or 3 cores but I don't know what effect that has?!
Is there any optimaization to do here?
I'm not running any separate intensive add ons, just my email and a browser and perhaps office2003 doc or two.

My system:
SW2009 SP5.1 x64
Intel Core i5 750
Gigabyte S1156 Motherboard
2 x 500GB Sata Hard Disk swap file on the separate disk
8GB Memory DDR3
XP pro x64

Hyper-threading increases performance on my Core i7 machine.

Hyper-threading is greatly improved on the current Intel cpu architecture over the old P4 cpu days.

One needs to be careful not to assume that what was true in the past is still true for today's cpu architecture.

Test for yourself with your files and workflow in SolidWorks to be sure.

Once SW 2011 is out with the CATIA kernel life should be good(read: multithreaded process). As long as it doesn't turn into vaporware like "backwards compatibility".

There has been no announcements by SW they are switching to the Catia kernal. Only a whole lot of speculation, at this time, from what was shown in the SW technology preview at SWW 2010.

I am very confident you will not be seeing it in SW 2011.

FWIW,
