Public bug reported:
Using VisualWorks to check some of my data files. With over 4 million
files, manual checking is unreliable and slow. When VisualWorks finds an
error I try to use Caja to view the directory and its contents. I
clicked the parent directory I wanted (../../../) and waited, and
waited, and waited. After 8 minutes I decided that Caja had crashed
since every Caja window is frozen. I searched the web for how to kill an
app. The Force Quit Button looks very neat, but installing one does not
work in MATE. I finally found Alt F2 and xkill which works works.
The only background activity was a Terminal command:
cp -anR "/media/robert/4TB Seagate 3/Users" "/media/robert/6TB Seagate 1"
which has been running for 3 days and I assume crashed because I see no new
directories showing up on the target volume.
Apparently Ubuntu MATE 18.04 has a design flaw. It does not handle large
external drives well and is slow as continental drift with a 6TB drive
mounted. Trying to copy 1 TB onto a 6TB drive takes over 6 days. Copying
3 TB from a 4TB to a 4TB takes only two days. This is an obvious design
scale defect. (An algorithm which works with a small set of data may not
work acceptably with a large set of data.)
Please have the developers examine their design and find out where the
flaw is. Have them plug in a 12 TB external USB 3 drive (the largest
commonly available size for desktop computers ) and see incredible
slowdown. (Using Caja to view a directory may take over 3 minutes to
show 247 files.)
