Speed fluctuation on GB network

[Greg0145]

I have 3 servers setup on a Gigabit network. They are the only nodes on the network. 1 server runs filezilla server while the other 2 use filezilla client. Both clients have databases, 1 of which is 170 GB and the other being 70 GB. I ftp these databases nightly as a backup. Backup time varies but both will normally finish within 2 hours. I've noticed while monitoring the server that the speed will jump around a lot, going from 5Mb to 80Mb a second. Normally, it will start off at 5Mb and gradually increase to 80 and then bottom out at 0 for about 3 seconds before picking up again. What would cause this? These backups could finish much faster if the speed remained constant.

Can the disks write the data fast enough?

Can the disks write the data fast enough?

I would think so. All servers are on a RAID 10 array with Seagate 15000 RPM drives. 8 GB of RAM.

Which versions of FZ and FZS?

Which versions of FZ and FZS?

Server 0.9.31

I thought we where using filezilla for the client piece but we are using standard command line ftp.

Standard ftp.exe from Windows? If so, try a real client, see if it makes a difference.
