Well, for one thing, 2.4.19 contains backported O(1) scheduler patch which
improves SMP performance by heaps as task queue is per cpu rather than one per
system. I don't think any system routinely runs thousands of processes unless
it's a web/ftp/mail server. In that case improved scheduling wuld help as
well..

Besides there were major VM rewrites/changes after 2.4.10 which corrected
almost all the major VM fiaskos on linux. For anything VM intensive it's
recommended that you run 2.4.17 at least.

I would say it's worth going for it.
