Do you mean the "plug-and-play" ones or the managed ones? Up to now, we run merely fast ethernet on every line, and we did not experience any real bottlenecks (at least not any caused by network) so far. I have to admit, however, we are running 4.2 here, not LTSP 5. Directly behind the server, there is a 100 MBit switch. From there, several lines go to different rooms and floors, branching again to different switches and sub-switches etc. We never had the feeling that the network would be too slow, all clients boot and run reliably until there are about 40+ online. There are some slow-downs obviously caused by other reasons, but network has always been ok. With one exception which suddenly came up during the last few weeks: We had short power break-downs from the mains during early morning hours caused by the electricity provider. The first switch is on the UPS with the server, the rest (naturally) are not. On one of the lines (only on this one), there was a significant slow-down in the hours afterwards. This error was reproduceable, though it had never occurred the years before. I am still looking for the reason. After an hour or so of using the network, the error disappears. It feels like there is one switch sending corrupted packages for a while or something similar. Once or twice, it helped to unplug and repower the sub-switch on this line, but yesterday it wouldn't help. It just "healed" itself after a while. So much about my experience. And if you have any idea what this mystery on one of our lines could be I will be thankful for any suggestion.
