Hi,
What is the practical limit to the number of async worker processes?
With SIP child processes, it seems to be about the number of available
CPUs in /proc/cpuinfo. After that--at least, per my testing--one
begins to hit the point of diminishing returns, presumably due to SHM
IPC and synchronisation issues.
Is the restriction similar in the async execution context?
no specific restriction.
Also, I haven't seen any degradation when using
more sip worker processes that cpus, which I do have always (at least 2
per CPU), because a worker can do quite a lot of I/O.
Cheers,
Daniel
