The feel is very nice and smooth - better than for example pre9-1. Also, doesn't have a problem than pre9-1 had, which is that it would allow the page cache to get VERY small, when it should have swapped pages out to preserve the page cache. However, this kernel still swaps out the wrong pages. It doesn't swap very heavily, but it does swap out some pages from running tasks which are later pages in. pre7-4 did not have this problem. It only paged out pages from (say) unused daemons, if such pages were available. However, with this kernel, xfs-xtt sit in RAM taking up 2.5 Mb, and it is never used. The kernel just never seems to get to xfstt, when scanning pages... It and other daemons just sit there consuming memory.
