Now it's becoming intolerable, so I aborted the dbench run so I could finish this email. This was with 2.5.65-mm2 and elevator=as. I'll repeat soon with elevator=deadline. I didn't try typing in Evolution with 2.5.65-bk under high loads, so I'll also give that a try. Summary: using ext3, the simple window shake and scrollbar wiggle tests were much improved, but really using Evolution left much to be desired.
