have got a ds3 mobo (onboard gigabit)connected to a netgear GS 605 switch connected to a Dlink DNS 323 via cat5e cable length of about 2 m
network utilization in Vista 64 bit is at most 31% ,which i think means it is transferring data at around 310mbs ?yes?
surely it should be a lot faster,
i know it will not get 1000 but i was hoping for over 400 maybe 500
would investing in a cat 6 cable improve things?
 
Depends how the motherboard connects the gbit controller, pci doesn't have enough bandwidth for full gigabit speed. If not cat6 then at least stp cable will help over utp. I think quality of kit is important too, between 2 HP servers over gigabit I get 843mbps (over a Cisco switch), I've never got close to that with cheap hardware...
 
surely you'll be limited by disk speeds on the two machines? Unless both disks can managed a sustained 1000+mbps?

that too, most home machines will fall over here as well, depends on what you're transfering...

This falls in line with his achieved speed. The average home drive can attain an average read speed of 60MBps, or 480Mbps. Taking into account overheads and other factors I think 300Mbps is a fair speed.

That is, of course if 31% network utilisation in windows is an accurate representation.

Correct ;)
 
thanks for the replies :)
i may invest in a length of cat 6 cable and see if that helps
still it is faster(or seems to be)over my old 100 mbs network
mostly mp3 and video files/folders being transfered .usually 4.3 gig in size ;)

try ipperf and see what it reckons link speed is...thats the real test, if it says faster then it's your hard drives...

where can i find that?have tried googling but failed :(
 
ONLY getting 89 mbs to my download m/c :(
not good is it?
played with a few settings on the properties of the dl mc card and now get 106 mbs.
can`t seem to connect to the NAS box though :( (to test it i mean)

What server ip should I be doing the iperf to?

IPERF needs to be running on both pcs
then enter the ip address of the `other` pc you wish to test
thats what i did anyway :)
