Commit Message

netty: reduce default worker ELG thread number by half, to number of CPU cores (#6439)

This would cut the amount of per-thread direct buffer allocations by half, especially with light traffic. This will also cut the amount of file descriptors that's created per thread by half.

Internal benchmark results (median of 5 runs) doesn't show any significant change:
