One thing I have notice and it's probably also due to the extra inherent disk caching built in to Linux the Mark mentioned.

Before the RAM upgrade with 3.0a7 I would get frequent short music pauses when entering the playlists menu (I think the disk was spinning up) or each time I'd type a letter in the search function. This is completely gone now probably due to the empeg not having to access the disk quite as much.

BTW: Could an admin delete my image please - I can't edit the post anymore. I apologise for making it so big causing everyone's browsers to stretch everything out.
