gigabit

I'm trying to maximize my LAN transfer speed. LAN cards and switch are all gigabit on a CAT 6 cable. Modes are set correctly to 1000 full duplex.

CentOS server

Testing with ftp from both windows and fedora, I'm only having the speed around 11MB/s. On windows I notice that the first few seconds of file transfer I'm actually getting around 25MB/s before it drops to 11MB/s

Can anyone please recommend me what my next step should be to increase this performance?

Are there any utilities I can use to test the file transfer speed without taking hard drive speed into consideration?

The only thing I know is the MTU which I will have to wait until the office hour is over before I can play with it. If there are anything else I should be aware of, please please let me know.

Thank you!
