My ISP told me to optimise my network connection using TCP Optimizer (Windows only). How can i check what values are being used and how can i set new values for MTU and RWIN ? "ifconfig" or "ifstatus eth0", at lest it shows the MTU. MTU is currently 1500 which is fine in my case. It can be changed in Yast:Network Devices:Network Card: Network Settings:Choose your card:Configure:General:Set MTU.
RWIN is the receive window, which specifies how much outstanding unacknowledged data is permitted. It's normally determined dynamically, by the receiver. MTU is max 1500 on ethernet, but can be much larger on other network types, such as token ring. Again, these days, it's usually automatically set, through path MTU discovery. One thing to bear in mind is that many Windows settings are required because of limitations in Windows and are not a consideration elsewhere. I get the following test results: Receive Window Size: 5888 (scaled) -> Your computer works with reduced Receive Window Size. This can result in reduced Download-Datarate.
I did: kdesu kwrite /etc/sysctl.conf and added the following lines: fs.inotify.max_user_watches = 65536 net.core.rmem_max = 8738000 net.core.wmem_max = 6553600 net.ipv4.tcp_rmem = 8192 256960 8738000 net.ipv4.tcp_wmem = 4096 655360 6553600 Is that the right place and syntax ? Different distributions handle this differently. Where can i look this up for OpenSuse 10.3 ? I rebooted but got no change so far. Ubuntu had problems with the high load of connections my p2p applications produce. Is OpenSuse a good tool for this ?
