Any way to speed up regeneration?

I work with pretty large assemblies (2000+ parts) and it starts to get pretty slow when adding new parts/saaemblies.  Any suggestions on how I can speed it up (without a new system!)?

I think I have a fairly decent system;

i7 3820@3.60Ghz

32mb ram

ATI Firepro V3800

solid state drive

I am running a single license installed locally but all my files are stored on a server.....not sure if this makes any difference.

Thank you for any help,

Colleen
