Hi.

Actually we buy a new laptop Dell Precision M6300 (Intel Core 2 Duo X900)with Redhat 5.3. for 64 bits, this have 8 Gb at RAM Memory and Nvidia Quadro FX 3600M with 512 Mb.

I installed too a VMware player for Windows XP and others CAE softwares, all runs ok, not perfect but runs well. but when we use at the same time 2 or more applications (including the VMware paler), the performance is poor.. the graphics performance down and inclusive the windows at the player display very slow (for example).

I don´t know if I need change a some parameters at the linux in order to inprove the linux performance.

I really appreciatte any comment.

Saludos

First things first: check if you are running a SMP enabled kernel:
# uname -a | grep SMP

Then again, whenever you use emulators and virtual machines, you kind of get crappy performance (at least that used to be the case last time I tried, about 2 years ago)

Thank you for yours comments.. I saw this ... maybe help us..

We are using SMP kernel

[root@ws62x7273 ~]# uname -a | grep SMP
Linux ws62x7273.vwm.na.vwg 2.6.9-78.ELsmp #1 SMP Wed Jul 9 15:46:26 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux

Here is some cpu info
