Re: scheduling question

Are there other tweaks to enhance the latency of networking? I don't mind a decrease in throughput, I'm in one of the rare cases where bandwidth is not the limit. There are these popular "bandwidth tuner" tweaks where people change the system's TCP buffer size with sysctls, would shrinking the buffers give me any latency improvements or will that result in dropped packets?

It won't help; the system already tries to give you the lowest possible latency. There's not really any more blood to squeeze from the stone.

It's important, back in the design stage, to take into consideration that you're going to be running in a multiprogrammed environment and try to take this into account there, rather than trying to tweak a system that can't give you guarantees to fit a design that assumes a particular value of "reasonable".

Obviously this isn't always possible.
