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?

Also, what is the point of core async_workers setting versus the
'workers' modparam to async? Are they supposed to equal each other? Does
one override the other?
