This is basically a followup to the "2.4.4 sluggish under fork load"
thread.
I am using Redhat 7.1 on a 128MB 400 MHz PII system. I have a
locally-built 2.4.4 kernel to which I manually applied the patch that backs
out the child-before-parent behavior on a fork. Namely, this patch:
<http://boudicca.tux.org/hypermail/linux-kernel/2001week17/1288.html>
However, even with this patch applied, I still see extremley jerky mouse
pointer behavior when I run any kind of job that does lots of forking. For
example, a kernel compile or even just the "configure" in preparation for
compiling XEmacs.
The same behavior, on exactly the same machine, did _not_ occur with Redhat
6.2/kernel 2.2.19.
I see that this patch has recently been merged into 2.4.5-pre1, but I am
concerned that it does actually fix the underlying problem.
Do others continue to see "jerky mouse pointer" behavior even with this
patch installed, or should I look for other causes? For instance, are
there known problems with jerky mouse pointer behavior under heavy swapping
load?
