Network Performance Fine Tuning in openSUSE & SUSE

6 Comments

  1. hi, is there a way to clean these network buffer?
    because when I running a LOTs connections.

    After two~three hours, I always get
    no buffer space available in /var/log/messages.

    I wish there is a way to clean the network buffer in opensuse 11.1.

    Thanks in Advance!

  2. excellent new openSUSE
    useful for tuning
    but I get an error message line

    linux:/etc # sysctl -w net.ipv4.tcp_wmem=”8192 87380 16777216″
    error: “Invalid argument” setting key “net.ipv4.tcp_wmem”
    error: “87380” must be of the form name=value
    error: “16777216″” must be of the form name=value

    linux:/etc # sysctl -w net.ipv4.tcp_rmem=”8192 87380 16777216″
    error: “Invalid argument” setting key “net.ipv4.tcp_rmem”
    error: “87380” must be of the form name=value
    error: “16777216″” must be of the form name=value

  3. default parameters are good, the maximum bandwidth available
    the problem Reno and cubic (terrible web page download)
    htcp the perfect solution for a single set

    sysctl -w net.ipv4.tcp_congestion_control=htcp
    or sysconfog.conf paste net.ipv4.tcp_congestion_control=htcp

  4. correctly
    sysctl -w net.ipv4.tcp_wmem=’8192 87380 16777216′
    sysctl -w net.ipv4.tcp_rmem=’8192 87380 16777216′


  5. the correct commands are:
    # sysctl -w ‘net.ipv4.tcp_wmem=8192 87380 16777216’
    # sysctl -w ‘net.ipv4.tcp_rmem=8192 87380 16777216’

    Thanks for the tips.
