We are running FreeNAS 8.2.0 (specs below), and getting extremely slow FTP performance. We have a 100/70mbps FIOS connection, yet FTP (remote) from the FreeNAS is never more than about 5mbps.
We tested FTP from a Mac as a server, and got around 40mbps, but it only streams for 10 seconds or so, then drops to 0 for a minute before resuming.
We tested with iperf -c iperf.scottlinux.com -P20 from the FreeNAS and got 60mbps upstream. Same from the Mac. So it seems the network is working fine.
Tried AFP and SMB, but results were worse than FTP.
Is there anything we can do? Do we need a stronger machine?
(Local transfers over LAN go at 800mbps or more, so I know the actual storage [zfs] is fast enough.)

If you've already tested the components on the local site and know you can get better performance, you might check your uplink, either on the current site's firewall or router. You might be running into bottleneck issues locally?
