Take the tour ×  I've recently set up Windows file sharing over
a gigabit ethernet network (I'm not using jumbo frames) with a
Samba server and a Windows Vista client. I've done a few file
copies, but the maximum throughput I'm seeing is 20MB/s
(megabytes, not megabits) which is about 15% of the theoretical
125MB/s maximum for the network. The server has a RAID array
that can manage about 75MB/s (the bottleneck is the PCI bus),
and the client can manage about 40MB/s in a disk-to-disk copy.
I should add that there was no other traffic on the network at
the time.  I understand I won't ever get the theoretical
maximum, but I didn't think it would be this bad.  What's the
typical performance of Windows File Sharing (SMB) on a gigabit
ethernet network?  Bonus points: what can I tune (besides using
jumbo frames) to make this faster?  share|improve this question
I've fixed the performance problems on my network: they were a
combination of a poor on-board NIC on the server and old NIC
drivers on the client. I'm now
