Server 2008 Transfer Speed

here scenario:

 

i have 2 servers; server server 2003 , server b server 2008r2

 

now server has folder on 500gb - 1tb

i want transfer folder server b

now not want interfere network put both servers in workgroup, ip scheme 192.168.1.100 & 192.168.1.101

 

i plug both servers gig switch (linksys small home user ones buy @ bestbuy) 

 

both servers have gig connection; server browse server b , copy huge folder over, getting speeds @ 20mbs after few minutes drop down under 15mbs

 

now both these servers running 7200 sata drives. 

why not getting faster transfer speeds?  understand won't solid gig transfer rate should getting pretty high.  both nics set @ auto duplex, tried setting nic's full duplex 1 gig not downgrade themselves. 

i have done on multiple servers , same results. switch dummy switch not managed.  tried changing out cables , used cat6 cables. 

 

hello,

the speed relies on piece of hardware badest/slowest reaction writing data new location. not network speed.

maybe article ace can see new network options on windows server 2008 doing , maybe changing default can you:
