Heavy emphasis on serving in the benchmarks:

Definitely worth the upgrade if you're into MySQL.

A few points:
First, 2.6.4 is still considered by most to be a BETA, a very good BETA but still just that. many production line people won't touch a kernel untill it is in the teens. Debain waited untill 2.4.18 to add it. I exspect better results as time goes on.
Seconed, the tester used the -j4 switch, this means do 4 simulanius actions. problem, the system is a Dual machine. Yah it has hypertreding which is crap, very inefficent. I think they would have gotten better results with -j2.
third, the 2.6 kernel is more, from what I have seen, better support for new hardware, and making user moddifing simpilar. I am not supprised that there are less then phenominal gains considering this. Also much of the improvements targeted the Desktop market.
Fourth, damn I loved thouse Samba Stats eh? that was sweet!!!
PS. I am tired and in the Middle of an Essay right now, I will spellcheck this later.
PPS. For the Jew, I was working on AJ's Quad Itanium and the AI64 2.6.4 kernel can support up to 256 proccessors. We talked about this before, just though I would give you the update. Cudows on the great benchmarking post :=D>:

Yeah, the Hyperthreading thing is up for debate. But if I remember correctly, he did it for both so that rules it out being a factor for one and not the other. Programs do work much better with Hyperthreading if they're optimized for it. Essentially, it makes the program think it has a complete cpu cycle when it's actually only using what's left over. Great for multi-tasking with winamp, word, etc. Not so good as an additional thread encoding, but it still does help.
