Willy Tarreau 8ae8c48eb0 MEDIUM: fwlc: re-enable per-server queuing up to maxqueue ... Leastconn has the nice propery of being able to sort servers by their current usage. It's really a shame to force all requests into the backend queue when the algo would be able to also consider their current queue. In order not to change existing behavior but extend it, this patch allows leastconn to elect servers which are already full if they have an explicitly configured maxqueue setting above zero and their queue hasn't reached that threshold. This will significantly reduce the pressure in the backend queue when queuing a lot with lots of servers. A test on 8 threads with 100 servers configured with maxconn 1 jumped from 165krps to 330krps with maxqueue 15 with this patch. This partially undoes commit 82cd5c13a ("OPTIM: backend: skip LB when we know the backend is full") but allows to scale much better even by setting a single-digit maxqueue value. Some better heuristics could be used to maintain the behavior of the bypass in the patch above, consisting in keeping it if it's known that there is no server with a configured maxqueue in the farm (or in the backend).		2020-10-22 18:30:25 +02:00
