The default window size (controlled by the socket buffer size) can be globally modified using sysctl variables: net.inet.tcp.sendspace: 16384 net.inet.tcp.recvspace: 16384 As you mention, changing this (and other things such as the amount of mbufs/clusters, etc.etc.) must be done considering the hw configuration and other issues. It is not a big deal to move the default to 32 or 64k, and I'd vote for that, but if a sysadmin is unable to have a look at this, then the problem is in the sysadmin, not in FreeBSD! cheers luigi ----------------------------------+----------------------------------------- Luigi RIZZO, luigi@iet.unipi.it .
