Serhiy Storchaka: "I'm not sure that it is worth to apply this optimization. The patch adds half a hundred lines of complex code for only 80 ns benefit. On my computer just incrementing an integer takes 100 ns."
Yury Selivanov: "(...) Right, but there are so many other things which contribute to the memory fragmentation.. I doubt that optimizing epoll will make any detectable improvement on that side."
To be honest, I expected better speedup before I ran the benchmark. That's why I repeat that any performance patch must come with a concrete benchmark showing a non-negligible speedup ;-)
I reject my optimization since it doesn't make the code faster. |
