Comment 1 Milind Changire 2018-11-26 12:30:03 UTC

Rationale:
Heavy IO keeps the single event-thread busy with reading messages from the
network and queuing them to the request handler threads. Messages remain unread
at the socket while the request is being queued to the request handler threads.
Time is thus wasted while messages accumulate in the socket buffers. To achieve
better responsiveness and thus avoid ping-timer expiry, it has been observed
that multiple event-threads help in achieving the same. Additional event-threads
help in improving system performance as well since they help in reading requests
sooner and get them serviced sooner than they would with the single event-thread
model.

Therefore the need to bump up the default value of event-threads to a better
value.
