winscp uploading speed suddenly droped.

Hi. From when i installed winscp and yesterday, i had no problems with it, the speed wich it was uploading at was a good 10/mbs and i was fine with it even tho my internet is way faster than that. But, yesterday i realised, that it started uploading files way slower than before, reching as low as 100/kbs.

I am working on a a project wich involves a lot of coding and the files i save are up to 20gb late at night so i need to upload my files to my console asap. Does anyone know why the upload speed suddenly droped to an avarage of 200/kbs and if there are any solutions? Thanks!

Can you transfer the files faster using any other client using the same protocol?

I tried FileZilla but after some time i got in the same situation as i have with winscp. One of my friend tried to upload too but today it happened to him too.

It was due to transfering large files in a ton of folders at once.
