Godbach, Thanks for the quick reply and suggestions. To enable multi-process mode does increase the capacity but limited by host NIC bandwidth. Can HAProxy be scaled to multi-node to host the same traffic?

The description of nbproc is as below: nbproc <number> Creates <number> processes when going daemon. This requires the "daemon" mode. By default, only one process is created, which is the recommended mode of operation. For systems limited to small sets of file descriptors per process, it may be needed to fork multiple daemons. USING MULTIPLE PROCESSES IS HARDER TO DEBUG AND IS REALLY DISCOURAGED. See also "daemon". -- Best Regards, Godbach
