"Con Kolivas, a practicing doctor in Australia, has written a
benchmarking tool called ConTest which has proven to be
tremendously useful to kernel developers, having been designed to
compare the performance of different versions of the Linux kernel.
He was kind enough to speak with us, explaining how he got started
on this project, what makes his benchmark unique, and how to
interpret the resulting output. Comparing the 2.5 development
kernel to the 2.4 stable kernel, Con says, "a good 2.5 kernel
(and that's not all of them) feels faster than 2.4 in most ways and
this bodes well for 2.6." The interesting results from his
frequent benchmarks back up this statement.
"Con also describes his high performance patchset for the 2.4
stable kernel, currently at version 2.4.19-ck9. This patchset adds
a number of performance boosting patches ideal for a desktop
environment, such as the O(1) scheduler, kernel preemption, low
latency and compressed caching..."
