Dear all, since a reboot about two weeks ago, on a server I use, all outgoing tcp connections are limited to about 200 kb/s. Incoming tcp and udp both ways is fine (1 GB/s) and also when using multiple connections simultaneously higher bandwidths can be reached. The server is running 12.3. The problem appears with apache, but also when testing with iperf. There is only one switch in between my machine and the server and switching the port with other machines doesn't help. Things I already tried: - disabling susefirewall, completely empty iptables - check tc (shows no entries) - playing around with tcp buffers, like discussed at https://fasterdata.es.net/host-tuning/linux/ - reboot :) Do you have any suggestions what could be the problem? Thanks, Robin
