quick question: does that mean I need as many children as the max number of 'requests/s' (at a given time)...?
By exampe, if I have up to 100 concurrent requests, do I need 100 children to prevent rejected requests?
It says "1 pending requests queued", and immediatly after, "queue overload".
What is the queue capacity?
In my test, I only had 5 images...
Sort of, you need one helper 'slot' for each concurrent request.
You can increase the number of 'slots' available by increasing the
number of children/helpers and the number of concurrency=N each can handle.
at concurrency=1 you need 100 children for 100 requests,
at concurrency=2 you need 50 children for 100 requests
etc.
This is mitigated further by caching the helper results for TTL=N time.
But worst-case is still 1 slot per request until the ACL result
mini-cache finds a duplicate.
