How to iprove Blender 2.5 Performance

My System stat’s.

*System : Windows 7 Proffesional
*Processor : Pentium®Dual-Core CPU E5300 2.60 Ghz
*Ram : 4 GB (3GB use-able since i have a 32 bit computer)
*Graphic’s Card : GeFore GT 220 1 GB
*Hard Drive : 13.0 GB free of 74.5 GB

Im trying to make Blender 2.5 run faster.
The only time it lagged is when i added a subdivision Modifier to 6 subdivision’s or when im redering a High Quality with Blender.

How can i improve the performance ?
And how can i switch from a 32 Bit to a 64 Bit ?

Thanks

Don’t use that much subdivision. I typically use only 2 or 3 for render and leave it at 1 for viewport.

To switch to 64 bit, you may need to partition your drive and install a 64 bit OS.
