Slow Gigabit LAN access
Hi
I opened a question a month ago on this issue and still haven't resolved it
My ASUS P8Z68-V PRO, Core i5-2500, 8Gb RAM, Windows 7 64bit system is slow on file transfers
Intel 82579V embedded NIC and SMC 8508T switch are both running at Gigabit speed
I recently purchased a Synology DS1513+ to store all my data
When I transfer a big file, 750MB in size, the transfer speeds average around 25Mb/s
When I view an avi, stored on the synology, using VLC, and transfer a similar sized file to the Synology, at the same time, the viewing is heavily disrupted, even halted.
Is this normal behaviour for an embedded Intel Gigabit interface ?
I installed a Logilink PCIe LAN interface to see if I could obtain better performance; apparently not.
Is the switch the bottleneck then ?
I presume that adding a second LAN interface in parallel won't make a difference on Windows 7 ?
Assuming I obtain a switch that can handle it, would teaming two interfaces together e.g. two same model network boards, provide a marked improvement ?
Thanks

Unfortunately nothing helped to improve the transfer speeds
Either my PC is creating the bottleneck, or the nature of the
operation which I have used to measure the transfer performance
places too much constraints on my infrastructure

Maybe disk system is as slow as it is and you cannot do much
Did you manage to try with other switch?

Other switch made no difference
Infact the transfer I was using to test the performance of my network wasn't really fair
the original file was actually on one of the Synology's shared drive,
So I was copying to another of the Synology's shared drives; the Windows 7 couldn't determine that both the shared drives belonged to the same system and thus used it's own memory to handle the transfer - thus soliciting the PCs resources to do so.
It's no wonder that the viewing of an avi file, also located on one of the aforementioned shared drives, is affected

Yes, I have installed the latest drivers, changed LAN cables, and ports
I have also tested various settings : Jumbo packet sizes, TCP offloading,, performance options (adaptive inter-frame spacing and Interruptive Moderation Rate)
I will try with a different switch
