Oh, if it's 2960 or 3750 switches, you could run into the "these switches have too tiny buffers to be useful" problem. Your server sends out a burst of packets to the client, with the full interface speed it can handle. Now if the link switch->internet router is slower (100m only) or has "other server" traffic on it, the switch needs to buffer these micro-bursts for a few ms - and that needs some amount of RAM, which the 2960/3750 just don't have... -> packet loss, bad throughput. (Unfortunately, design goals for the 2960S/3750X were different than "get this fixed", so the buffer size is the same) gert -- USENET is *not* the non-clickable part of WWW! //www.muc.de/~gert/ Gert Doering - Munich, Germany g...@greenie.muc.de fax: +49-89-35655025 g...@net.informatik.tu-muenchen.de
