Decrease in the speed of copy

When copying the files, why the copy speed keep on gradually on the decline, even when no other programs are open?

Example:

Even in the absence of back ground programs running on my PC (Windows 7 home basic 64-bit, 3 GB of RAM, 320 GB HDD, Duo Core), when copying a folder GB 2.5 with 1800 files to a USB stick 4 GB of my PC. got the following:

copied %(approx) - speed in MB/s
1% - 5.40
10% - 5.72
25% - 5.77 (max)
30% - 5.17
40% - 5.00
50% - 4.81
70% - 4.0 (min)
80% - 4.0 until the end of the transfer

On the whole process was almost constant at 1.21 GB RAM and CPU use was between 2 and 15%
Windows Explorer used about 94 800 KB
While remaining constant processes at a total price of approximately 87 500 KB

Hi Praveenkumar.pon.p,

·         Were you able to transfer files from computer to USB key with a good forward speed?

·         Have you tried to plug the same USB key with a computer different, is the transfer speed is still slow?

If the transfer rate is the same with the other computer, there could be a problem with your USB key.

I recommend the clean boot and try to transfer files.

  • By getting only 10% of the speed of download of airport Ex

    My local ISP offers service of 1 Gbps, and actually, I always get 700 + Mbps when connected directly to the wall outlet.

    But once I connect it with an Apple Airport Express (model A1392, bought Dec 2015), the speed drops under 100 Mbps (connected via the ethernet port) despite a request from Apple express airport rises to 300 Mbps. And if I connect via wifi, the speed decreases to near 60Mpbs. While it is always respectable, it completely makes my empty 1Gbit/s connection of sense.

    Is it possible to do the job express airport closest to its full capacity (in terms of speed)?

    But once I connect it with an Apple Airport Express (model A1392, bought Dec 2015), the speed drops under 100 Mbps (connected via the ethernet port) despite a request from Apple express airport rises to 300 Mbps.

    This is because the Ethernet on the AirPort Express ports are valued at 100 Mbps. Download speed will not be "accelerate" transitioning between WAN port on the base station of the Express and wireless audio. However, the rate of data transfer between local wireless devices should reach the highest rate.

    Even from the last airport of 802.11ac base stations Ethernet ports, which are the nominal bandwidth of 1 Gbps, realistically only have a data rate rate about half of that. If you want to get a little closer to what your ISP offers you will need to look in the products of other manufacturers at this time.

  • How can I control the speed of the fan on the IX2 - DL

    I'm trying to find where I can adjust or set the speed of the fan on the Lenovo Iomega IX2 - DL.

    I make a copy of the large data, and internal temperatures are higher I would like to see.

    Is there a way to define or to control or adjust the speed of the fan at different temperatures in the box?

    Thank you.

    Hi snoopypa30,

    There is not a way to change the fan speed manually. The fan turns on when the device has reached a certain temperature. Is your ix2 in a well ventilated area?

  • I can load the speed in real time?

    Hi, guys.

    I'm working on my project now. Right now I use PCI 7344, UMI-7764, AC/DC motor sevro, their amplifiers and the camera of the UAB.

    I try to repair the braiding point machine to weave leadership x. usually the Plait point oscillates around a point in x direction.

    At first, I need to get the position of the point using cam USB, I've done braiding. The positions I got the cam of the UAB is in real-time.

    Then, I need your comments the position of the motion control loop. I intend to use the position to calculate the speed that responded to the questionnaire, which is real-time, too.

    Engine going this speed. Thus, it is supposed to get that engine will decrease or increase depending on the weaving point moving.

    I don't know if we can do it. I have yet found the relative position.

    Anyway, thanks in advance. Any idea and the idea is really appreciated.

    Guangli

    Guangli,

    as the camera of feedback is coming from a USB camera and with the during the calculations necessary to analyze the images, the behavior of your system in real-time is probably not very tight. Delays and jitter of the additional movement control operations are probably in the same order of magnitude as the delays and jitter, introduced by processing the image. If it's okay with you, can do the following:

    1. Load a maximum travel speed and acceleration/deceleration of the values for the axis
    2. With "Load Velocity override", you can pass the speed between 0 and 100%. Transitions of value axis a velocity to the adjacent spire to the value of the acceleration that you defined before.
    3. If you need change the direction of travel, you need to use 'Load speed' and 'Motion to start. " This operation is much longer that a speed of loading a substitute value, but in general you should not call this sequence too frequently.

    I hope this helps.

  • make the shortcut for the influence of the speed

    Is there any way to speed up the process of the evolution of the influence of the speed of keyframes?  As a shortcut, or a shortcut key?

    I found I like influence of 70% on most of my ease-ins rather than the default of 33%, but the seconds it takes to set my preferences are starting to add up.

    Thanks, Paul

    II have never heard talk of a way to change the default relieve values (even though I think many of us would like TO replace the easy ease generic value), but I was able to somewhat mitigate the time-wastiness of the curve of edition with a script called ' copy paste facilitated "or something like that. I believe that it of free (like most of the best scripts) and allows to highlight a set of keyframes (or 3 or 4...) and copy only the memory speed curves. Then you can glue them to any other keyframes you want any parameter's (ideal to match the curves of transformational speed effects or path of shape morphs). The scriptUI window is nice and compact, so you can paste it anywhere for quick access.

  • The behavior of copy (.png files) screen when using TextEdit and printing

    I have long used the method to copy and paste texts and/or pictures to TextEdit and print files .rtf or .rtfd below:

    I use the command-control-shift-4 and the cursor to select things and paste into TextEdit.

    That stopped working in the Sierra.  I tried several methods (PDF format conversion, fall in Pages and Numbers, for example), but nothing worked: the Canon PIXMA MX922 printed on a white sheet and left the box of small characters with text "filter impossible."

    There is no new printer driver on the Canon site; However, there is a new driver IJ Scan Utility and I downloaded it already after that installation of Sierra and the scanner works fine, as also directly print something (e.g. on the Web).

    Now, after several days of testing and I was wondering, I tried this yesterday:

    Instead of the above command, I used (which I do when I want to save it to the desktop) command + shift + 4.  I copied the file .png from office, dropped in the TextEdit, printed, and... IT WORKED.

    Copy and leaving fall directly in the TextEdit and printing, is so not working, but let fall the same screenshot on the desktop and copy and paste into TextEdit and it print shops.

    I noticed several other annoying problems to Sierra, some I've reported here (communities), some didn't.  Business-as-usual: first version of an upgrade is full of bugs, which 'disappear' in future versions, until a new update is made available, the loop continues, continues, and...

  • What is the speed of the hard drive of the 2015 2 and 3 to merge disks partition?

    I was looking through the Apple site and was wondering about the speed of the drive in the iMac in car merger. On their site it says that the 1 TB Fusion drive has 24 GB of Flash memory, and 2 models to and 3 to have 128 GB of Flash storage. But it does not say what the speed of the hard drive partition, which is what I want to know. It is 5400 RPM, or even 10000 rpm or 7200 RPM? I don't know, but I want to know. If anyone here knows the answer to this question, I would appreciate a response. Thank you.

    I have seen it reported that the Fusion drives are all 7 200 RPM.

  • Software updated 2 days ago. He stuffed the speed up to a point, I had to borrow someone's HP to complete a task. Very disappointed

    After the update my macbook snaps every minute and the speed it exceptionally slow to a point as I sit for 5-10 minutes waiting to open finder or safari to open. This update plush speed of my macbook. He now works at all. Display and all that remains is very good.

    I have an important assignment due this Friday, fortunately someone lent me their HP to complete my task.

    very sad and disappointed with this, Apple.

    Please provide a solution.
