I'm making the helper children configurable for on-demand startup so a
minimal set can be started and allowed to grow up to a max as determined
by traffic load.
Growth is triggered by helpers dying or requests needing to be queued
when all helpers are full.
Drawback is that this fork can be quite expensive on larger squids, and
then momentarily stops all forwarding under peak load. But overloaded
helpers is generally worse so..
Ideally the concurrent protocol should be used as much as possible,
avoiding this..
Yes, when Kinkies muxer is ready this and that can combine to a very
powerful boost for the helpers.
* start 1 child synchronously on start/reconfigure
* new child helpers as needed in bunches of 2
* maximum running kept capped at 5.
?
I would increase the max to 20 or so.
This affects helpers for auth_param, url_rewrite, and external_acl_type.
Why not dnsserver?
Yes, it's affected too.
