Copy is insanely slow

[ags1905]

Using FreeCommanderPortable_2024_Build_901.paf.exe

Scenario
- copying browser profile in a different location on the same disk
- disk is an SSD of 500 MiB/s read and write

Browser profile
- 1.431.918.766 bytes
- 12.343 Files, 759 Folders
- browser was not running

Results
Double Commander - 7 seconds
Windows Explorer - 9 seconds
Unreal Commander - 10 seconds
Free Commander - 600+ seconds. I stopped the copy operation at about 60% and 10 minutes. Selected copy method was Use FreeCommander.

Can someone reproduce this? Not the seconds, but the absolutely insanely long times FC manages to get compared with other file managers.

FC is noticably slower (I wouldn't call it insanely slow) especially when there are lots of small files involved.

Windows FileExplorer: 0:51min
FreeCommander: 1:41min

19.511 files, 2.713 folders

I admit faster is better, but ....

Improvement in FC copy (using FC method) can be achieved by selecting "Copy" tab instead of "Files" in the copy window. You will see that it is much faster be on "Copy" then on "Files" with the list of files. Next impropvement you can achieve by disabling refresh of files completely. If you are copying more files from one panel to other and you can see how FC stop for a while when refreshing the panels. It is anoying to remember to click on "Copy" tab from "Files" which opens automatically, but I did not find how to disable the feature. Seems that handling the listbox with the files which are copied makes delays in copy process.
