Dear Experts,

our new server Ethernet connection seems too slow, 0.5% of it is Ethernet connection is utilized. 100MB takes 5 minutes to copy.

server has 4 Ethernet.  all four acting the same.  coping files within the server is fast and normal.

would you say, this is caused by the driver installed or anything else.  
Windows Server 2008 OS recently installed.

this worries me as this server becomes Files server for our staff

What is the ping delay from source and destination ?
Are you having the same issue with other server/computers connected with the same switch ?

Hi

- Simple start point.  

Look at your "Resource Monitor" on the server.  Initiate a file copy and see if any bottle neck occurs in either CPU/Disk/Network/memory.  You can select/deselect processes to analyse what's going on.  This may give indication where to look next.

- Are your Network cards teamed correctly?

- Is the switch configured to auto negotiate or is it set at 10Mb - Check port settings on your switch.
- Check file copy timings from different computers

1) run "gpedit.msc" from Run dialog.
2) Navigate to Computer Configuration > Administrative Template > Network > Windows Connection Manager
3) Click "Disabled" radio button in the Minimize the number of simultaneous connections to the Internet or a Windows Domain option.
4) Reboot your windows, you may see noticable speed improvement for Cable and DSL modem except 100Mbps Fibre which is already fast enough and might unlikely to see any gain.
