2.5's Performance Improvements
Kernel trap reports on
Andrew Morton on 2.5's performance improvements.
"For the uniprocessors and small servers, there will be significant
gains in some corner cases. And some losses. Quite a lot of work
has gone into "fairness" issues: allowing tasks to make equal progress
when the machine is under load. Not stalling tasks for unreasonable
amounts of time, etc. Simple operations such as copying a forest
of files from one part of the disk to another have taken a bit of a
hit from this. (But copying them to another disk got better)."
