But if all of these textures are stored in RAM, there should be NO lag, regardless of how many toons you are running - or at least less lag than even an SSD.

Unless, of course, these textures take > 4-5G that an 8G system should have left over after 5 clients. Then you are still paging from disk. I just have a hard time believing there are THAT many, even in shat.

hmmm
