(I didn't understood that the first time I read this email). It might be good to disable all tcp optional headers.. Also there might be important to look at issues such has: - mtu size - tcp window - set the don't fragment flag (this can offload the routers and optimize the mtu for the whole connection path) - use the BIC algorithm (from what I've read, that's my default choice nowadays... but for some specific workload there might be better algorithms) kind regards! -- Miguel Sousa Filipe -- gentoo-performance@l.g.o mailing list
