Depends on how the tasks are split between, usually the sip workers may
have to do more (e.g., filter bad traffic, respond to keepalive, maybe
also authenticate, ...) and the traffic getting on evapi is not the same
as the input volume.
Cheers,

Thanks, Daniel. Based on this, is it reasonable to
allocate the same number of both kinds of workers?

Hello,
I think there are two types of processes: "evapi dispatcher" (1 process
always) and "evapi worker" (can be many controlled by workers mod param)
and the resume of the transaction should happen in the later. The former
gets the data from sip workers and writes to evapi tcp connections, then
reads data from them (i/o event loop) and pushes to evapi workers. (iirc
:-) )
Cheers,
Daniel

* https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users Hi,
When a transaction suspended by evapi_async_relay() is resumed, in which child processes
is it resumed? Is it in the dedicated “EVAPI RELAY” workers defined by the ‘workers’
modparam to ‘evapi’?
If this is so, just trying to work out the concurrency implications and the optimal size
for the worker pool for maximal throughput. It sounds, at first glance, like it should be
roughly similar to the sizing considerations for listener children. Thoughts welcome!
Cheers,
— Alex
