Take out a stopwatch and time then. if they are 4.5 seconds tell me, if they are 12.5 seconds tell me. That's all that I have been asking for. That's all the convincing that I need. And please time it after a reboot...not after a trial run or two when everything is cached. I mean you tell me it was 1/2 way through...but halfway through what?? 5 seconds, 1 minute, 1 hour, etc?

Please send me the link to the article that you are referring to. You only posted a picture earlier, I haven't had a chance to read it to weigh in on it. But I'm not entirely sure what impact his concepts are on how fast your computer actually is. But I'd really like to read what you are talking about so we can be on an even surface.

Here Mark Russinovich describes the inner complexities of Windows file transfer...

"Copying a file seems like a relatively straightforward operation: open the source file, create the destination, and then read from the source and write to the destination. In reality, however, the performance of copying files is measured along the dimensions of accurate progress indication, CPU usage, memory usage, and throughput".

I have already spent dozens of hours testing and recording the file transfer rates in my new Win 7 x64 computer some of which I have shared here and you have flatly rejected them as unacceptable proof even though I presented you with very credible and authoritative evidence that justifies and shows those results to be credible. So as to prevent both of us from wasting each others precious time here are my conditions for discussing this subject with you any further...

1) Do you accept Mark Russinovich's simple explanation about the real truth of how file transfer actually works in Windows in part that it requires and involves both CPU usage and memory usage in excess of 1 GB RAM? (Also please remember that my computer is quite different from yours in that its core i7 930 processor always idles at flat zeros for all 4 cores)

2) What I've already done and shown proof that Win 7 applies high amounts of RAM to obtain these accelerated file transfer rates and the average speed over the duration of the file transfer would do nothing to invalidate the fact that the peak recorded speed of 430 MBps did occur. Do you agree?

3) Are you willing to accept the results of highly fallible stopwatch tests over the unimpeachable screencaptures you have already dismissed as flawed?

This isn't telling me anything. It just says that you need to weight and evaluate the progress bars, system usage and throughput to get the overall picture.

Before I agree to what you have paraphrased, I would like to actually see the story that you are referring to.

With regards to my computer, yeah we are a bit different...however my Q9500 Quad Core Intel CPU idles at 0, is overclocked as well, is also running 8GB of RAM with 4-4-4-12 timings at a 1:1 FSB/CPU ratio, and has an SSD drive for the OS.

Yes, I agree an average would not highlight the peak.

Yes, I always trust the stopwatch. If you copy 200MB and it takes 10 seconds, you were copying at 20MB/s. Perhaps you momentarily went faster or slower...but the average copy is 20MB/s.


I guess if we have to set ground rules to continue our conversation, I want
1). To know how long, in seconds, it takes you to copy a few GB worth of data

2). Can you accept the fact that your file copies cannot honestly go any faster than your hard drives can supply that data?

3). Can you please post a link to the article that you keep discussing. I feel it's being misinterpreted, but my attempts to get to the source keep failing.

Edit: actually I'm done discussing this. Sometimes you reach a point where you realize that no matter what you say or do, both parties are incapable of following what each other is saying. I'm sure in many regards, we are both right and both wrong...but we are clearly talking about 2 different things. Rather than resort to name calling and getting nasty, I'm just bowing out as I'm 100% comfortable in my assertions. I don't think anybody on this board has seen a mechanical spinning hard drive capable of supplying data at over 400 MB/s.

I apologize to the rest of the members of this board, for dragging this out so long and derailing the conversation. What can I say, I'm passionate.

Now it seems as though we are finally in agreement. I'm sure that we each have much better things to do than carry on like this and I hope that we will be able to meet and discuss other subjects under more favorable circumstances in the near future. I'm sorry that we got off to a bad start. Hopefully my exuberance over getting Win 7 just a few short weeks ago hasn't gotten in the way of someday being able to rectify this unfortunate riff between us.

Hmm, an illuminating discussion? no doubt

Now, I have another piece of intelligence. I have moved my page file on a separate partition on my second hard drive. It made things a bit faster. But a much bigger difference is between copy and move operations. Copy is way faster, about two or three times faster. So now I copy and subsequently delete, rather than move, since that takes less time - if we are talking about large files.

At the same time, transferring files to my USB flash drive is now way slower than before. So this moving of the page file seems to be a double-edged sword.

Found this on the net:

Quote:
Go to
  1. Control panel
  2. System and Maintenance
  3. Administrative tools
  4. Run services shortcut


Once the services program loads find the services called Background intelligent transfer service and stop it

also right click on the same service and click properties then change the start value to manual or disabled this should also fix the network problem and USB copy and paste problem

Thanks Lomai, but I have this service on manual start already, it's not running.

The USB transfer rate must be related to the page file since it became slow after I moved the page file to another disc. And what is it with the "discovering items" nonsense when I am copying a single file by dragging it in Explorer?

Does the speed increase again when you move the paging file back?
