Hi,
Just found a particular workload that yields
a terrible performance.
Running two simultaneous diff like this:
diff -uNr linux-2.2.18-pre11 linux-2.2.18-pre11.new
diff -uNr linux-2.4.0-test9-pre7 linux-2.4.0-test9-pre7.new
And then trying, for example, to open a terminal only
succeeded after one of the diff ended (a couple of minutes
later).
Attached is the 'vmstat 1' output. The file starts after
the two diff are running and I'm waiting for the terminal
to come up. When the number of blocked processes drops
to 0/1 is when one of the diffs ended.
This is an UP machine using ext2 on IDE.
