Hi, i can transfer files via ftp(no errors in wireshark) at 10,5mbyte/s, but if i use scp its only about 5mbyte/s and wireshark shows: TCP Previous segment lost at packet 63,153,160,221,222,223,1392,1517,.... now if i copy a file to a sshfs mountpoint speed jumps between 400kbyte/s and 4mbyte/s wireshark reports: TCP Previous segment Lost 50,63,140,167,208,418,.... TCP Retransmission 76,183,385,487,.... What could that be? Client: CoreDuo 1.6Ghz Server: X2 3800+ both with minimal load, doing nothing else. 4gb testfile greets |
