I'm very interested in hearing what you find from your benchmarks.
I've been wondering how much better KSE currently is in CURRENT ever since
I started running 5.1-RELEASE on my laptop a few months ago. But I don't
have the time to do extensive benchmarking, and I don't have a spare machine
to run them on. (hey, I need my laptop for work.)
I've also heard that 5.x ships with added kernel debugging and such. If that's
true, it might be a good idea to turn that off (not sure how.).
Also, running similar benchmarks on a 4.8 system would make a good comparison.
