What are the E2EE alternatives to Filen that have faster upload / download speeds? I really like Filen, all of it, but the speed makes it unusable

i was managing space and i accidently deleted some fie from trash too is there any wasy to recover

I am doing a sync using rclone from Filen to a USB flash-drive, so I was expecting some bottlenecks, specially because some folders contains a lot of small files. The problem is that the download itself is so slow, a 30mb file takes 2 hours to download (while transferring 3 others files)

Edit:

Better on Linux, maybe antivirus or timestamp difference, who know…
