File Transfert too slow

minuccio63 · 2025-05-05 12:52

Hi everyone, I installed Q4OS Aquarius with Trinity desktop on a Hp 6730S laptop but I have a slow file transfer problem, same file, same external drive, same USB port, in windows 10 the file is transferred at 22.8 MB/s while with Q4OS it is transferred at 1.2 MB/s why? How can I improve the transfer, Thanks

Interesting discussion here: https://www.reddit.com/r/linux/comments … ncredibly/
Both systems work in different ways. There is certainly slowness when it comes to wanting to eject a usb thumb drive in GNU/Linux compared to Windows which is mentioned in the link I posted above. At least in Windows you know when it is safe to remove a USB drive you have been writing too. I wait for the USB icon to disappear in Windows before unplugging the thumb drive (Windows 7 Pro 64-bit!). There is only an indication that it is safe to eject in GNU/Linux yet the hardware activity light continues to flash, indicating that files have not yet been fully written to disk.
I did find this 4 year old post of interest:

Im running Windows and Q4OS KDE and Im not having any issues with speed/mbps. Ive had issues with some drives in Linux. Have you tried a different drive to test?

minuccio63 · 2025-05-07 12:29

@crosscourt
I tried both with an external Toshiba USB 3.0 HD and with a Pen Drive and the problem is the same. In Windows the same file is transferred much faster. Could it be a question of the USB drivers?

crosscourt · 2025-05-07 18:48

Are your USB drives using exfat or fat32? Exfat is definitely the faster choice for Linux.

Hi, the same thing is happening to me. I want to create partitions or transfer files to the USB and the transfer is very slow.

crosscourt · 2025-05-07 21:59

Could be a file cache issue. Is the speed better or worse when you do large file transfers vs small file transfers? Cache takes a beating with large file transfers, depending on how much ram you have in your system and the USB drivers involved it could be quite slow. that are that are

Im running systems that are Intel 5th and 8th gen systems and the file transfer speeds are close but Windows does perform better.
I mostly use SanDisk drives and havent had any issues.

Before switching to Q4OS I used Ubuntu for years, recently I used 22.04 and I never had this slowdown, the PC is still the same, an HP 6730S, a bit old I know but for me it works fine, even under Ubuntu I used the same external HD, a 2GB Toshiba, I only noticed the slowdown under Q4OS and I used the same transfer file. I would like to attach some images but I don't know how to do it

In Q4OS this is the velocity:

and this in Windows with same port, same HD, same PC, same File... same all

Please try to run command:
$ rsync -ah --progress the_same_file.avi /tmp/
and post back the result

Well, the internal transfer speed is fine. Now try the same command, but with the storage in question, the same port, device, file as within the Windows run:
$ rsync -ah --progress the_same_file.avi /the_external_drive_mount_point/

Moreover, replug the external device in question, run commands and post back its output:
$ lsusb
$ dmesg | tail -n15

Is this issue specific to the Toshiba device ? What about the transfer speeds on some other USB devices and USB ports ? You can get the corresponding values using the "rsync" command.

minuccio63 · 2025-05-09 11:50

No, the problem also occurs on pen drives, I noticed the slowdown from the pen drive and I thought it was the pen drive's fault, that's why I tested it on the HD because it's faster, on this PC I've always used Windows and Ubuntu in dual boot and I didn't have this problem before installing Q4OS

Is the transfer speed over USB slow across all USB ports and all devices you connect ? Are there any exceptions ?

We are unable to reproduce the issue on Q4OS Aquarius. The rsync command shows tens to hundreds of MB/s on a regular USB port when copying large files. So it seems that the issue is hardware related or specific to your installation.

It is difficult to investigate a hardware and non-reproducible issue, so we would need more debugging information in the form of a "reportq4" debug file, see https://www.q4os.org/forum/viewtopic.php?id=3502

minuccio63 · 2025-05-12 11:11

Since I can't sit still and I like to solve problems, I uninstalled Q4OS and formatted the partition and installed Ubuntu 22.04 from Live USB. I did the file copy test (always the same) and it copied the file (about 470 MB) in 6 seconds... I did the test several times and it always maintained the same speed.
Then I reformatted the partition, and from the pen drive I installed Q4OS-5.8-x64-instcd.r2.iso, I updated the system and did the file copy test always in the same way... file copy speed 25-35 Kb per second!!!! At this point since in Windows the copy is fast, since in Ubuntu the copy is fast the problem is in Q4OS!!!!!! If someone can give me an explanation I would be happy otherwise I am forced to return to Ubuntu.....

It would be helpful if you could install a regular Debian 12 Bookworm, run a test, and send back the result so we can compare Q4OS and its base Debian. This will allow us to narrow down the source of the problem.

We are unable to reproduce this issue and therefore investigate it. Transfer speeds are fine on Q4OS.

minuccio63 · 2025-05-12 11:35

Ok Thanks now i try to install Debian and report the news...

q4osteam · 2025-05-12 11:35

You could also try to install Quarkos https://quark-os.sourceforge.io/ based on Ubuntu and test the transfer speed.

minuccio63 · 2025-05-14 11:52

Update the circle is narrowing...
I installed Quarkus latest stable version 24.04 Plasma and did the transfer test always the same file from home to external HD in 8 seconds, since I didn't like Plasma I downloaded the version of Quarkos Trinity... installed and updated.... file transfer 60 Kb/s (I'm at 10% and still missing 1:46:03) The problem at this point is in Trinity... I hope it can be useful

q4osteam · 2025-05-14 12:28

This is really valuable, thanks.

What desktop profile did you apply upon the Quarkos Trinity installation (pure, live, basic, full) ?

Would you please make some testing on your Quarkos Trinity installation:

1.
Reboot and login
Stop Trinity desktop:
$ sudo systemctl stop tdm.service
Login to console and check transfer speed with "rsync"

2. Try to install Plasma desktop using the Desktop profiler https://www.q4os.org/dqa016.html on top of your Trinity installation, login to Trinity desktop and proceed rsync test.

The results would be a clue for us as we are still not able to reproduce the issue, even within Trinity desktop.

minuccio63 · 2025-05-14 13:45

Ok the installation profile has always been BASE
Tested with rsync = low speed
Installed Plasma... both in Trinity and Plasma file transfer OK even in Trinity now it is faster than Plasma, should I leave it like this?
