Benchmarks with trivial epoll based web server showed noticeble (more
than 40%) imrovements of the request rates (1600-1800 requests per
second vs. more than 2300 ones). It can be described by more
cache-friendly freeing algorithm, by tighter objects packing and thus
reduced cache line ping-pongs, reduced lookups into higher-layer caches
and so on.

Is that an hypothesis, or did you get a chance to gather cache stats with something like http://www.hp.com/go/Caliper or the like on the platform(s) you were testing?
