However, I found in one of the IBM redbooks (http://www.redbooks.ibm.com/redpapers/pdfs/redp4285.pdf on page 131) that disabling tcp sack and dsack is recommended on a samba box working on a gigabit LAN (when samba host and clients are in the same LAN). In one case it helped much, in the other it did not change anything, so you should try on your own: sysctl -w net.ipv4.tcp_sack=0 sysctl -w net.ipv4.tcp_dsack=0 Andrzej
