How long shoudl it take to copy a 10GB file server to server?

Ok, I know the question is somewhat subjective. I am just looking for a ball park estimate from a real world environment, not a calculation.

Here is the equipment...

Quad Core Xeon 2.8Ghz, 2GB RAM, SAS 146GB 15K RPM Drives, Windows 2008 R2 Full Install/Not Core, 1GB NICS.

All that is between the two servers is a 24 port 1gbit switch.  All ports are set to Full Duplex 1000bit.  Minimal traffic on the switch and servers.

Using Windows Explorer copy a 10GB file from server A to B.

How long does it take?

On my environment. 10.5G  it take 2:30 minutes with 55% 1Gbps adapter utilize

Damn...I'm taking about 2 minutes longer.  I'm thinking it may be the TCP off-load.  Do you have any off-load enabled?

Thanks

2 minutes longer?  How about network utilize?  is it 50 minimum or lower?

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.

Could be AntiVirus Software.

Could be TCP Offload.

Could be the type of files you are copying.

Could be a bunch of variables.

Most likely AV or TCP Offload.

I would update drivers and firmware for network card. If this doesn't help disable Ofloads

Go to Network Card properties click on Advance Tab disable all Offloads here as well and reboot

Why is <5 mins an issue? getting approx 33MB/s end to end isnt too shabby!

What are you trying to achieve by copying 10GB between servers?

JoeNuvoCommented:
I guess, 10G maybe just example.
if his system copy "big file", which should reduce standard MS Windows issue of "many files" overhead.
then 50% slower than same type of system may imply some problem.

and let say if file size is 100G instead of just 10.
2 minutes longer might become 20 minutes longer which is significant number.

However, BladesAway, FYI : on some of my servers, network utilized when copy big file keep swing between 20-50%
Never find out reason yet, since those copy process is schedule and have plenty of time to finish.
