Description (last modified by ossi) (diff)

Original submission:

When you copy/remove lots of files, the midnight gets too slow 
because of thousands of screen redraws (per a second). Terminals 
are slow and disc is waiting.

It would be nice to limit the redraw of the copy/remove window do 
an user defined time (e.g. 200-500 ms). This could be easy to 
implement (and you dont need threads or something like that - just 
one "if" and time measurement).

Check this out - touch 100000 files and try to delete with midnight 
and after that with the "rm" command. Feel the difference?

Why wontfix? Curently removing lots of files in mc takes minutes and with "rm -rf" only 1-2 seconds.

mc has a "verbose operation" option which enables progress output in the first place.

but the idea to implement event compression (repaint skipping) is entirely reasonable - nobody can follow more than five filenames per second anyway. so just omit progress updates if less then 200ms passed from the previous update.

i think it's good idea..

comment:12 Changed 10 years ago by DvanDellen

Disable verbose in the options doesn't make that much difference, actually takes more time to copy +-7GB
Any tips? Is this fixed in a newer version?(current 4.8.3)

Could this be related to #3247 (incl. its comment 3)? I'm afraid even in non-verbose mode mc just does way too many screen updates (prints every filename in the dialog), probably rate limiting them would noticeably speed up the actual operation.
