Description Jeremy Katz 2001-02-20 19:00:13 UTC
Maybe it's just me, but 2.4.1-0.1.9 feels a lot worse than 2.4.0-0.99.x
with interactive performance.  On my laptop with 192M of ram, there seems
to be a lot of RAM being used for caching at the expense of using a lot of
RAM for swap.  I have extremely noticable lag when switching workspaces in
X and in bringing up any new application, the latter of which is also
generally accompanied by heavy disk thrashing (much heavier than I would
account for just by loading the app).

This defect is considered MUST-FIX for Florence Gold release

Comment 2 Michael K. Johnson 2001-02-21 17:53:53 UTC
Assigned to sct to investigate vm balancing

Comment 3 Stephen Tweedie 2001-02-26 18:33:34 UTC
A lot of bad VM behaviour is cured in 2.4.1-0.1.14 (the Wolverine kernel): does
that fix things for you?

Comment 4 Jeremy Katz 2001-02-27 02:09:15 UTC
0.1.14 is later than the kernel shipped in wolverine but is currently in
rawhide. It does seem to be a bit better balanced thus far, though.  Thanks
