Unusually slow hardware during flow simulation

I am trying to track down why my hardware is running so slow when solving a flow simulation. I am currently working with my reseller on the problem, but I wanted to check if anyone here could help.


I ran a flow simulation benchmark and got 3646 seconds compared to the reseller's 2.8GHz laptop at 368seconds - a 10X difference! I have tried turnning hyperthreading off, but that doubles the run time. When I run the usual SW bench mark, my times are slightly better than average for my workstation, so I don't know what the problem could be - any ideas?


Here is my information:


Lenovo Think Station S30

Windows 7, Service Pack 1

Intel Xeon CPU E5-1650 0 @3.20GHz, 6 core with hyperthreading for “12 cores”


64 Bit

Nvidia K2000 Graphics Card

240GB Intel SSD


Solidworks 2014, 64 bit, Service Pack 2.0



From the SW benchmark running 2013 SP5.0, 64-bit

Graphics: 18.6 Sec

Processor: 35.5 Sec

I/O: 23.3 Sec

Overall: 77.4 Sec


Rendering: 21.3 Sec
