Hi Kandiedan,
Thanks for working on this PyFFi Tool.
I do have a Quad Core, so ill give it a try and do a serie of tests.
In order to compare results with other users, we need to make sure every user PyFFiies the same files.
Here are the files i would suggest to PyFFi (since everyone has these files, they are from the Meshes bsa

)
Meshes.bsa --> architecture\anvil\meshes\architecture\anvil
Ive been PyFFiing the first 20 files from the Anvil folder:
altarcloth01.nifanvilbasemantdoorframe01.nif anvilchaindollholder01.nif anvilaltar01.nifanvilcirclebench01.nif anvildoorframe01.nif anvildoorframeint01.nif anvildoormc01.nif anvildooruc01.nif anvildoormcanim01.nifanvildooruc02.nif anvildoorucanim01.nif anvildoorucinteriorload01.nif anvilfgsecondfloor.nifanvilfgfirstfloor.nifanvilfgtopfloor.nif anvilhousecavein01.nifanvilhousegeneric01.nif anvilhousegeneric01_far.nif anvilfightersguild01.nif
My computer:
Q9450 @ stock speed (2.66GHz)
4 GB DDR3 1333 mhz (9-9-9-23 if im correct

)
Asus 4850 512 MB stock speed
OS: Windows Vista 64
Time to PyFFi => about 2 minutes
CPU ==> 50% when running 2 PyFFi scripts , maxing up to 70%
No problems however, it seems to run fine.
Used 2 cores first, will run the other tests either tonight or tomorrow night.
EDIT:
2e PyFFi test run, now PyFFied above files using 3x PyFFi via the ini configuration.
Time to PyFFi => 1 minute 20 seconds (the last mesh seems to be a problem here, its a big mesh i guess

)
CPU ==> 75% when running 3 PyFFi scripts , maxing up to 85%
