230 minutes to transwfer 12GB through home network?

[de8212]

Does that sound about right?

Any tweaks or settings that could possibly help out for large file transfers?

Both machines are XP pro. Just using regular copy/paste now.

If my math is correct you are getting around 7Mbps of speed which seems pretty low. Can you give us more details on your network hardware and configuration?

Both machines are XP pro. Lan cards are 10/100. The machine sending the files is plugged into a smc router (wireless, but wireless is disabled). The otehr machine is hooked into a switch which is also hooked into the SMC router.
Not sure what else????

Try eliminating the switch as a factor and plug both computers directly into the SMC router.

yea i do similar amounts all the time, never takes more then a few minutes

Try hard-coding the Speed\Duplex settings in the computers. I've found that some Ethernet adapter and router combos don't like Auto-sensing and do a LOT of negotiation that is unnecessary. Try that and let us know.

Try other (pre-made, commercial) cables.

The first suspect should always be the cabling: it is the most likely problem with speed issues on the LAN.

Good Luck

I placed both cables into the router and I am trying to copy ~6GB and it says 130 minutes. SO that's not better.
My house is pre-wired with cat6 and I have one commercial cable conneted to the main pc but I do have one I made going to the other pc. Can't really swap it out now becasue I don't have another one that long.

Not sure how to hard code Speed/Duplex. Any more detailed info or other ideas?

In Control Panel>Network Connections> properties you should find some sort of option that allows a value of 100 FULL DUPLEX to be set.

Normally it would take less than 10 minutes per gig depending on if it's 1,000,000 tiny little files, or a few really big ones.

Could also use a crossover cable or something else if it's a temporary move.

If not, just start it and go to bed....

On the machine that I am sending the data from it was set to Auto Detect. I went and and set it to Full Duplex/100Mbps.
On the machine that the data is being sent to it was on half duplex. I changed it to Full duplex.
I'll see waht it does.

that would most certainly cause trouble.

common causes of performance problem are bad cable (especially home made ones) and some kind of duplex mismatch - where a nic or switch have different duplex settings (like auto on one end and forced full on the other)

Well that didn't seem to help. Of course the cables in the wall are cat 6 that a friend and I put in. I can't imagine them being the problem. A couple of other ones are ones that I made. I owuld figure they either work or don't, is that not true? I mean could they be "partially" bad?

Anything else?

the cables probably weren't terminated properly. You can take off the jacks and make sure that the correct color is in the right place (orange to the orange, white/orange to the white/orange) Happens all the time.

one last thing is to set all network cards to auto speed/auto duplex - that would eliminate and mistmatch problems.

One of the cards does not give the auto detect option. Just TP Full Duplex, TP Half Duplex, BNC and AUI.

Anyhitng else????????????????????

sounds like that is a 10 Base-T card and not a 10/100 card. If there is no auto or speed settings then I'm positive that is a 10 Base-T card (in addition to BNC and AUI - that 10 Base-T only)

 

[de8212]

Spidey is correct. I am also setting up Remote Desktop and somewhere in all the confusion of switching screens I incorrectly read the other machine off to be 10/100.

I actually found out a while ago but just got around to installing another nic.
Now I'm copying 3.77GB in ~7 minutes. Much better.
Thanks for all the help and can someone please explain the "math" part of this so I can calculate some other things.

thanks everyone.

Just use base 10 - it will work out about right with overhead, etc.

100 megabit = 10 megabytes a sec.

1000 megabytes = 1 GB = 100 seconds.

12 GB = 1200 seconds.

or in your case...

12GB = 12000 MB ini 230 minutes or 13800 seconds.

12000/13800 = .87 MB a second or multiply * 10 to get megabits/sec.

8.7 megabits/sec.
