I am tunning these three parameters:
I have clear what’s the meaning and what to expext of the last two, but I dont know how this pool size has effect:
- I have set to 1 and I see that more than 1 keepalive connections for an upstream (with several ips returned) are created and holded according to idle timeout and max requests
- If I leave the default value of 60, the behaviour creating/opening connections is the same
Is a kind of global parameter or something internal that is shared in the memory of every worker ?
