    Purpose of tcp_low_latency?


    What effect does setting tcp_low_latency=1 have on performance? What are the advantages and disadvantages? I am working on a low latency RHEL 4.5/5.1 system and tcp_low_latency is set to 0.

    Thanks.

    Google is your friend.

    If set, the TCP stack makes decisions that prefer lower latency as opposed to higher throughput. By default, this option is not set meaning that higher throughput is preferred. An example of an application where this default should be changed would be a Beowulf compute cluster.

    Wow, so unhelpful. Everyone just quotes the same manpage info back, to this question. No one actually answers with an explanation of what it actually does! Grrrr... :/
