I recently purchased two new manchines. Both OS's are Windows 7 64 Bit. I setup a file share on one of them. I noticed when I move files to and from the computer I usually get about 20-30MB a second and network Utilization is around 10-20%. How can I push the nic to or at least close to 100% utilization. The files being tranfered are from disk arrays capable of tranfers way hight than this. I have proved it by tranfering to USB 2.0, 3.0 and Esata. The Network controller or onboard both showing PCIE 1gig. I have a cisco 3750 gig switch and i'm connecting them at 1gig. I don't have QOS running and I setup jumbo frames on it. I tried setting the MTU on the interfaces to 9000. I tried using jperf to test transfers. I am getting about 30MB/sec. I guess I'm down to the OS, onboard nic or some configuration I'm missing.
Does anyong have any helpful hints to max out the transfers?
I tried turning to 1000 full on both machines, but still have the same issue. I also turn off all energy efficient settings and green settings. The newest drivers were installed from the web during my initial configuration less than a month ago. I will reinvestigate the drivers though.
When I changed the MTU it was originally set at 1300 on both machines. I had never previously changed this so I'm not sure why its not at 1500. At either 1300 or 9000 the performance is the same. I try 1500 too just to say I did.
In PC's (home/business's) I have never seen a PC transfers above 50%, servers are different... And to increase your speeds, you are going to have to dig deep into the TCP/IP stack, and get rid of any kind of excess fat...
Most of the links are for "gaming", but they should help with file transfers as well... Just some thoughts, it might help.
