Hello, all.
I thought about patch simplification, and tested version
without BufTable and dynahash api change at all.
It performs suprisingly well. It is just a bit worse
than v1 since there is more contention around dynahash's
freelist, but most of improvement remains.
I'll finish benchmarking and will attach graphs with
next message. Patch is attached here.
