[feature request]different number of threads for comparison and actual synchronisation

[detomine4321]

Hi everyone,
I am using freefilesync for synchronising two remote folders and I must admit it is working quite well.

I just have a request, if possible :
I have made several tests with the multi-threading setting (I am using the donation edition) and while it makes the comparison really fast (it scales up to x10 according to my limited testing), it actually slows down the synchronisation phase (I assume it is because of the lack of bandwidth between the two remote locations).

So long story short, would it be possible in a future version to use a different setting for multi-threading for the comparison and for the synchronisation (in my case, 4 and 1 respectively would mean approximative 15 minutes saved per day).

Thanks in advance for your time and efforts (it is a fine piece of software you have here).
PS : apologize in advance for my so-so English
