Very Slow Upload Speeds

[m0ck]

I'm using Zoom File Uploader version 8.6.3 Registered, and I'm experiencing very slow upload speeds.

When uploading files through Zoom File Uploader, my upload speed is usually only around 2–5 MB/s. However, when I upload the exact same file using MEGAsync, I get speeds of around 40 MB/s.
My upload speed is 500 Mbps.

I've tried chomikuj, dropbox, mega and other hosts and always get the speed around max 5 MB/s which is very ubstable and constantly goes from several Kbps/s to few Mbps/s
Any advice or suggestions would be greatly appreciated.

MEGA uses simultanous uploads in parts. My program does not do that. It can upload only files simultaneously. Otherwise speed for 1 part should be similar.

You can try to download my app into a new folder and test with clean settings.
Try different buffer size, usually 512kB should be fine.
Also compare speed for other sites too.
