One's an upload, the other is a download. Stuff is handled different on each end but the file still gets there.

ITguy,

computers are connected together through a router which is connected toa DSL modem. So they talk to each other through the router.

HappyFriar,
I was just curious if there is a speed difference, I understand that technically the processes vary.

Thanks

Wired through a router (1gig speed) ?

Answer is still NO

Think of it as a pipe, the maximum flow is detemined by the smallest section of pipe regardless of which way the water flows.

ITguy,

Thanks.

bob,

Thanks,

Speed would depend on protocal used and bandwidth available.

With most LAN's today it's all a "no reason to think about it" issue. You don't need to setup your FTP server on one machine or make sure you have the right zmodem protocol version. :D

It's a matter of throughput, only.
One way to test this in a true bidirectional environment is with a utility called NetStress.
It needs to be installed and active on both network machines.

"Is there any difference in copy speed between PUSHING a file to another computer or PULLING a file from another computer?"

Why not time a few copies back and forth and then you could tell us? Note that due to caching, the first of multiple copies might be a bit slower.

It's a matter of throughput, only.

You're ignoring the computers drive read/write speed, media you're using, quality of the connection, what is happening on each end.. .a TON of stuff!

Of course, when the internet is involved, there seems to be a definitive, serious difference between upload and download speeds (about a 6 to 1 ratio).

Why is this different?)

"You're ignoring the computers drive read/write speed, media you're using, quality of the connection, what is happening on each end.. .a TON of stuff! "

We may have slightly different definitions of the word "throughput." While it may be useful to check disk-to-disk transfer rates (such as with an FTP utility) afterwards, the thing we have real control over is maximizing and maintaining the actual network throughput. Thus the goal is to isolate and quantify network performance node-to-node. This goes tenfold for wireless networks, where traffic congestion, interference, and overhead are the rule, not the exception.

I'll concede, use of the word "only" does not cover every conceivable odd situation, but checking for and measuring hardware and disk read/write bottlenecks would best be done on-machine, not over the network.

I wrote a little .bat utility that uses fping (from Sourceforge) as a quick test that doesn't require a receiver application running on the remote node. It's useful for comparing relative bidirectional throughput to network routers and switches, media servers, or other computers, just about anything with a LAN IP. It's basically a ping flood utility (some routers and modems with DOS blocking enabled may reject it). Just by comparing throughput to the router over various WiFi channels (beacon strength is not an indicator), I am able to stream HD from my notebook to the WDTV Live, which I wasn't able to do before.

Apologies in advance for taking this so far off-topic.

Mudsmith, it depends on what sort of connectivity you have with your ISP. My cable provider gives me 5Mbps download but only 768Kbps upload. That's the ~6:1 ratio. They figure that the average home user is much more likely to pull lots of large files down than to send much data up.

I think they also limit the upload speeds to deter business use. If you want to run a web server from your house or business then you have to pay for the desired upload speed.

Cos the internet is using a modem and an asymmetrical speed difference in upload and download (depending on ISP). This is also much slower that the big pipe around your home/office LAN, which is independent of 'direction'.

If using HDDs, there should be no speed difference at all, unless one computer is incredibly slow for some reason, and even even that would likely be symetrical.

"Cos the internet is using a modem and an asymmetrical speed difference in upload and download (depending on ISP). "

You guys are getting WAY off the original question.

The question was between PC's on the same router. The Internet and the ISP are absolutely irrelevant to that question.

The answer to the OP's question is: "No".
