Actually I'll give you something slightly different, and more to the original question. I've taken two tcp captures on the Samba server machine. Both transfers were performed using the Windows 2000 cli "copy" command pulling a 36MB avi file from a share on the Samba server. The first test was a single stream copy. The second test was a dual stream copy of the same file concurrently to two different destination directories. I also had iftop running during the tests. The single stream transfer maxed out at just over 64Mb/s. The dual stream test maxed out at 92Mb/s. Following are the two tcpdump output files using "tcpdump -p -s 0 -w FILE port 445": http://www.hardwarefreak.com/smb_single_stream http://www.hardwarefreak.com/smb_dual_stream The file sizes are 38MB and 76MB respectively. The raw outbound link speed behind which my web server sits is only 512Kb/s so it'll take a few minutes to pull the files, probably about 30-35 minutes or so for both files. My apologies for any inconvenience this may cause. -- Stan -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
