100mps network using 0.1%(1mps) where's the probable slow down?

transferring from pc 2 pc thru router. only .1% or 1mps where would the speed be slowing? My CPU was running @ 50-60% while transfering.

My hard drive or his?
My FSB or his?
My CPU or his?
My IDE's or his? he has faster spec CPU and M/B but same drive.

Would a game utilise the bandwith better than a transfer?

1 more q': is 1000mps network any good if we cant even use a fair amount of the 100mps network, we mostly use it for games but occassionally we transfer large files (patches etc.).

Cheers everyone

Can't say for sure but I'd say its a driver problem at one end. I'd re-install drivers for both cards, and if you have time re-do the network settings.... I.P's etc.

Hope this helps

Do you use a firewall? Sometimes I find that software firewalls can cause a massive network slowdown under windows (I use Win2k) if not configured to "firewall off" for your LAN. I have particularly found this with ZoneAlarm, even when all the correct stuff has been allowed access sometimes you need to switch it off. An alternative to this is to shut down your firewall, start what you want to do, and then start the firewall again. ZoneAlarm will leave alone any services already running over the network when it starts up, and therefore won't block them.

outside of hardware issues llike cpu v cpu, ram and the NW cards, it could be that you've set the operating systems to "index" files on each pc.

from memory this was the case for windows 2k for example.

whenever you changed something on one pc the other pc had to update it's indexing of you pc - hence the network traffic.

well thats possibly what's going on anyway...

Cheers, I do use zonealarm so will try that and will search to turn off network indexing on both PC's,

Cheers boys and girls - just needed some more thinkers on it.

It should be quick. :D I don't think any of these other things will slow down transfers. Any indexing would be done after complete file transfers; not between packets.

What does ifconfig show for "errors"?

Have you got a spare cable to try? Or try different ports on the router. Or a crossover cable and eliminate the router.

At school the computers there have XP and when you go ctrl alt del and then the networking tab it only goes upto 1% but no perfomance loss?

OK so what would a normal network speed look like transferring from pc to pc? Maybe its normal to use 1%??


Anyone know the 1000mps transfer speed in reality? or should they be running at 100mps and 1000mps or 100%?

Cheers

I dont think ive ever seen any file transfer at 100mps over a network. I reckons all that mps is for Bandwidth. Usually transfer a 400meg file at 3-6 mps

Well I continusly get 8MB/s when I transfer files from one PC to another using 10/100 links at 100.

Remember if you are using XP then turn off QOS service as it will reserve some network space for itself so you can't go full speed.

QOS only reserves 20% but we can only seem to use 1-2% on a good day! CHeers

So after looking, heres the truth about QoS...

And you actually believe MS? After turning it off I noticed a good increase and so have my mates. And this is just transferring files from one PC to another. We have never turned it back on and will not.

OK, now I believe you! Since you tried it, cheers.
