If you can use all that memory for index, I would say RAM. For long running indexes (to get
os cache populated), MMAP will do just as good  if you have any file system worth using.

Subject: MMapDirectory vs RAMDirectory

Hi,

On a 64-bit platform with 30gb RAM and 8 real CPUs, should
MMapDirectory or RAMDirectory provide better search performance on a
5gb index?

Cheers,

Michael
