Horribly slow COPY on SMB share
I am not sure this is related to this forum, but I think that it's the best place to post it.
I'm having an unknown problem ever since I started working with pfSense (switched off FortiGate-60).
My network is as follows:
WAN (has no effect here, it's an internal network problem)
LAN (FreeBSD 7-STABLE, Samba 3.0.28)
OPT1 (Windows 2000 Server, Backup)
All connected to pfSense through 3 NIC's and operating at 100Mbps.
pfSense has a rule to allow traffic on port 445 (MS DS) from OPT1 -> LAN, with no states.
All other OPT1 -> LAN traffic is denied (though no speed increase was monitored without it).
There's no traffic shaping in effect at all.
Using the above configuration, I am able to list files on the Samba share (LAN), and then I want to copy a 300MB file from LAN to OPT1. The copy takes around 160 minutes. That's a bit below 2MB/min. which sounds terribly wrong! The same hardware and software combination were used with the previous FortiGate-60, also connected to its 3 NIC's, and it ran pretty well! I guess it's something in pfSense's configuration?
Thanks for your assistance in advance.

It might be your nic's (intel is best)
File transfer with windows can be a pain so i prefer using something else.
To test your speed you can use SMBdownloader ( no install )
Total Commander is also a nice tool.
pfSense uses fxp's (which are Intel's), LAN uses Broadcom's (it's brand-new HP 380G5 server) and OPT1 uses Netfinity (IBM x335 server).
Again, everything worked with the former firewall… No hardware/software changed except the firewall.
This is odd!!
And, it's a backup robot that is installed on the Windows (OPT1) server that automatically copies all data on the SMB share (LAN), so no other protocols or programs would fit my needs.

Trafficshpaing on multiple interfaces is not really supported in 1.2. Turn off the trafficshaper for your situation.
As I mentioned earlier, there's no Traffic Shaper active on any interface…
Anyone have any idea on how to solve this particular problem?
Meanwhile, I've allowed all traffic on the firewall between these two NIC's, with no Traffic Shaping whatsoever, and I still get the same rate. I will probably connect both computers with a cross-cable eventually if this is not resolved… :(
OK, I think I've resolved this problem. I've done the following steps:
Tweaked the Windows Registry using numerous HOW-TO's found on the Internet, especially TCP Windows Size, Request Buffer Size and TCP 1323 Options.
Rebooted the Windows server.
This has resolved the problem, and copying a 300MB file now takes approximately 2 minutes!
Thanks for everyone's assistance and time.
