[leonmt]

Describe the problem: [A clear and concise description of what the bug is.] In the same file and network environment, downloading files through the SFTP plugin is slow, but copying files through the SCP command is fast. To Reproduce: [Steps to reproduce the behavior]

Upload speed is also very slow, usually 500kb/s where in other places I can get 17MB/s

I confirm this bug !

[kalelbot]

Same bug experiencing!

[VeddySama]

Is this bug not going to be fixed?

[Frontesque]

Still having issues. It's maxxing out at 5.5MB/s on my gigabit network (I'm getting 120MB/s with the same machine on FileZilla)

Same for me, uploading from Win11 to a LXC on proxmox. All machines are in the same network.

So I assume the code for SFTP is here: https://github.com/Eugeny/tabby/blob/master/tabby-ssh/src/session/sftp.ts Can we e.g. increase the buffer size for downloads, up from the current 256Kb to something larger? The whole thing is looping I/O in TypeScript, which might be sub-optimal, but maybe a larger chunk size might help?

Confirm the same bug too. I have used iperf3 to test the speed limit on my server and clients , it has over 960Mbits/sec . while download some file from the same server , i got 2.65MB/sec speed. That is weird .

Same, I copy files from other terminals in LAn through Tabby at a very slow speed, it forces me to use PowerShell to finish.
