ubuntu 22.04 and 1TB hdd with a considerably fine hardware status.
problem still remains, matter of fact i just lost a whole bunch of data because
after screen froze i just unplugged the usb and then i had to re-create the
ntfs volume from scratch (gparted) to be able to mount it again.

I haven't had a problem with this for a long time, but it started again
about a month or two ago, on 22.04 system.
It does not matter what is the source and/or destination (NFS shared
drive, local HDD, local SDD, USB, whatever), or is same or different
drive used as source and destination, when I
I can report, that i have the problem now on my NAS system.
What a mess...

Title:
Ubuntu slows down and hangs while copying file
Can't believe this bug dates all the way back from 2014 and 8 years
later in 2022 this is still a thing! Not only that the bug has nobody
assigned to it and is of "undecided" importance!
My experience is appalling even by juggling with the vm.dirty_ratio and
other dirty bytes values and my system
[EDIT]
I still have the but if my Chrome/Chromium and associated 30 tabs have been
started. Even if I close them. Even has htop shows I just have 2.5G/11.6G used.
Duplicate of

# Objective
Monitor dirty files memory,
Change to more suitable values.
What it does: change from default 10 and 50%.
My understanding:
If `(vm.dirty_background_ratio/100) * memory size > largest file size`, then it
should be ok.[reference needed]
Note: `memory size` may be *available* memory
[EDIT]:
* PC hard drive is an SSD as well (upgraded 2 years ago).
* Transfer speed from internal SSD to external SSD. (See attached image)
** declared: 40MB/s
** observed: 12kB/s (I hand measured 87sec/1MBs)
** slowing factor: 3000+
* Dirty little hack : unmount then remount external disk hack

### Software
Ubuntu 20.04. < bug still on 20.04. Agree with #103 #101 #94 #78
### Hardware
Several posts above mentioned hardware, RAM or RAM updates, so I will document
mine as well.
Initial > ASUS K401UB :
- Intel Core i5-6200U (2.3GHz)
- 4GB DDR3L
- 1TB HDD,
I don't know if this helps, but I have experienced similar issue. Might
be a different reason, though.
1. connect phone (Oneplus 6) to computer and start large file transfer from
there (~10GB or so).
2. Insert memory card to memory card reader on the computer
3. The system is really unresponsive
My day was saved by #107 comment, I tried everything mentioned in this
issue, and always get a lagged mouse!, mi machine es a laptop lenovo
L480 12GB RAM, with SSD ( a very capable machine), after I deactivate my
swap partition (20GB) (swapoff -a) my system starts working as a champ,
thanks
Me too. I turned the cache back on and don't notice the freezes.

Thanks @peterrus!
I can confirm that using swapoff completely removes the hanging and
stuttering during heavy disk IO.
I don't see this only during file copy. Extracting archives, for
example, or saving virtual machine state to disk cause the same kind of
stuttering and hanging. It was

Status
After upgrading my RAM from 12GB to 20GB I get significantly better
results. Even with swap enabled I get a lot less UI lockups, and even
when I get them, there are significantly shorter.
This might be logical as I the issue seems to happen when swapping and
because of the increased amount of RAM
I have tried to eliminate using a swapfile (as is default since Ubuntu
18.10) instead of a swap partition. Results are as follows:
Using a swap partition (10GB) instead of a swapfile seems to increase
dd's writespeeds with about 10% and seems to decrease the amount of
stutter and lag, but doesn't
Alright, I have run some more tests:
I copy a file in my (unencrypted, ext4, on root partition) homedir with:
dd if=testfile_8gb of=testfile_out status=progress
(I made the testfile using dd if=/dev/zero of=testfile_8gb bs=1M
count=8000 status=progress)
While running this Xorg/Gnome3/Mouse/Any
I have been running some comparative tests between distro's on a
Thinkpad T450S with a i5-5300U and I think this is related to CPU
throttling.
The issue seems to occur on:
- Ubuntu 18.04 (5.0.0 stock kernel)
- Ubuntu 19.10 (5.3 stock kernel)
- OpenSUSE Tumbleweed (5.3 stock kernel)
But not on
Ubuntu 18.04 here.
Copying big files from SSD to usb device takes too long after the copy
percentage reaches 99%.

Ubuntu 19.10 here. UI, including mouse, freezes on copying big files within the

The suggested change of

Wow, six years and still now solution or even someone working on this. I

What is needed, that this bug is processed, triaged and maybe resolved?

I recently replaced Win 8.1 with Mate Ubuntu 18.04.3 LTS. Copying large

internal to internal. When the freeze happens, all devices connected on
