Optimum gigabit network transfer speeds

Hello guys!

Testing a new server setup

I'm currently getting transfer speeds of a minimum of 40 MiB/s using Filezilla FTP server to move large files. (Starts @ about 70 MiB/s but then drops

This is about 330 Mbps

This is 1GB to 1GB, both wired to a D-link Dir-868L (high end)

eg:

File transfer successful, transferred 2,339,731,796 bytes in 66 seconds

Is this OK ?

I would say No, but that speed can be hampered by a few things. With everything optimized you can approach real gigabit speed (1000mbps). Using onboard gigabit adapters and not tweaking anything I usually expect the 700-800mbps range.

I don't know much about FTP, though.
 
How are the computers connected? If they're connected to a router wirelessly or an older router that can't handle the speeds, the gigabyte connections on the computers become overkill.
 
I usually see 108-110MB/sec with no other heavy transfers going on. Try disabling intterupt moderation and maxing out the buffers within device manager for the network adapters.
 
I like using FTP because it allows me to easily create users with specific access to specific paths, all using different passwords

I just tried the same file using "windows", pc to pc, and it only took 23 seconds, which is about 100 MB/s

Wonder why filezilla is slowing me down ?
 
Filezilla has some nice logging, very verbose is it showing errors that might be slowing it down? Are you running a Pro level of Windows? You can create user accounts with lusrmgr.msc and assign permissions to folders with it just as easily.

I havent looked into FTP vs SMB deeply but perhaps increasing the window size might help or disabling TCP heuristics.

Yes, it is Windows 7 Pro
I have created 4 user accounts, each to have access to a specific path
no problems there
However, I cannot figure how to enable only READ + Write permission for those accounts
NO DELETE permissions
I can do this @ a user lever, but as a share, I don't see any options available

Dunno, but at least there's nothing wrong with your network. 😎
 
Ideal transfer speed including overhead with 9k Jumbo frames using SMB2+ (which adds a small amount of overhead) is roughly 117.5MB/sec or 940Mbps. Transfer methods which do not use SMB can probably eek another few Mbps out of a transfer.

If you are getting below that, I'd suspect either bad cable, crappy NICs in the machines or machines that just can't cope with faster transfers (either memory, CPU or storage subsystem).
