Caja and Nautilus umacceptably slow for more than 50 files

[Robert Pearson]

The latest update of Caja seems to have replaced the existing algorithms with ones that do not scale. Right clicking takes >3 minutes to open the menu if there are more than 300 files in the current folder. Opening a directory with 12,000 files takes so long that I get to catch up on my reading.

Also Caja frequently crashes (even more often than Chrome).

This was not a problem in earlier versions of Ubuntu MATE (18.04 through 20.04.3 without the last 3 updates).

Thanks, but please stop reporting bugs this way.

Use "apport-bug caja" command next time.

For current bug execute "apport-collect 1951220" to add necessary information.

Thank you for your bug report. What Ubuntu serie are you using and what updates did you install that created the issue?
