We can't tell if that kind of load is normal for your box; please don't make us guess from the context. Also please tell: - hardware (cpu/ram/nic at least) on old/new cluster - software (kernel/OS) on old/new cluster - HAProxy configuration on old/new cluster - what is the actual number of concurrent sessions? > Has something changed in kernel 3.11.5?

It seems you have a load problem; what happens if you disabling splicing? Are you using splice-auto or forcing splice by configuring splice-request / splice-response? Could be a kernel thing, could be a NIC limitation or it could simply be a higher load due to more concurrent connections ... Regards, Lukas
