Is 3.2 a significant regression from previous releases, or is 3.4 just faster? Your wording only indicates that "older kernel is slow," but your tone would suggest that you feel this is a regression, cf.
It's definitely a regression. I'm trying to pin it down, but the 3.2.0-24 kernel didn't do the CPU drain down to single-digits on that client load test. I'm working on 3.2.0-30 and going down to figure out which patch might have done it.
Older kernels performed better. And by older, I mean 2.6. Still not 3.4 levels, but that's expected. I haven't checked 3.0, but other threads I've read suggest it had less problems. Sorry if I wasn't clear.
