Posted June 29, 200816 yr When I transfer a big file (40GB) via a shared folder, then the speed infact (size/time) is only 100Mbit/s, while with other applications I can transfer files at 800Mbit/s. I have checked a lot of parameters at perfmon, and found that at the receiving end, the speed of disk writes is limited (only in MS file sharing) to only 12,000,000. If someone knows a solution to this please let me know. If someone can repeat my experiment - You would need disks that are capable of at least 30MByte/s, and a gigabit network. Send a file that is large enough so that the transfer will take enough time to check stuff at perfmon. Send it via a shared folder, and watch in perfmon the receiving disk write speed Bytes/sec. If the speed gets over 12,000,000 then maybe it is only me. The max speed I saw was 16,000,000, but usually it was 12,000,000. Please report relevant hardwares types, and OS. My two OSes are both w2k3 standard 32bit. Regards. SMB, CIFS problem.
