Hello, I've started to switch to a multiproc setup for a high traffic site and I was pondering a potential stupid question; What is actually balancing the balancers so to speak? Is it Linux itself that balances the number of connections between the instances? I'm running in a vSphere/ESXi machine with 5 vCores, where I use core 0 for interrupts, 1-3 for http and 4 for https. Since it's a VM, NIC queueing and IRQ coalescing seems to be out of the question, so I'm just leaving the core 0 for interrupts and it seems to work fine. I just bind cores 1 through 4 to the haproxy processes and leave 0 out. However, the three haProxy processes serving http requests, they are taking 10%, 30% and 60% respectively of the load. It's always the same cores taking the same amount of load, it never changes, it's somehow "decided" that one process takes 10%, the other 30% and the last 60%. What decides this "balancing" between the haproxy processes? Can it be the VM setup? I've never run a multiproc setup with haProxy on a physical machine, so I don't have any reference to such a setup.
Thank you. Regards, Stefan
