Whenever files are moved / copied to / from my laptop’s hard drive,
the cpu usage goes up to 100% and top shows very high usage for
process file.so causing system freezes.
Is this normal on lvm+luks+ext4 on a hard drive?

I’ve been using LVM with LUKS and “ext4” for years. And the slowdown seems too small to notice.
However, if I am copying between the “ext4” file system and an external “ntfs” file system, then that is slower and there is a lot of CPU usage for the “ntfs” file system.
You mention “ext4” for one side of the copy. You have not mentioned what’s on the other side.
Though I was using ntfs, same happens while copying data
within the same ext4 partition the system is installed on
I used expert partitioner during install
I’m not noticing a problem with “ext4” to “ext4”.
Well, okay, if I copy a 4G file (a linux iso), that does take a noticeable time. For small files, I don’t see a delay.
If data being copied exceeds a few gigs, the usage shoots up
This partition is 1.4 TB , I was copying a folder of 25 GBs
The installer had recommended xfs for /home
Lots of small files takes more resources then one big file of the same size.
Copy from the command line or a GUI (which)
luks should not have a big hit but some
Same happens when copying files in same partition via cp
from command line.
The system is lvm encrypted container which contains / , a data partition
which has symlinks to xdg directories, and a swap
Does this need bug reporting? How do I find out what is causing this?
