Transfer speed decreased

[superuser7777]

Communication between winPC and phone slows down when in a wifi environment. This occurs with all file formats and file sizes.
Termux：15M/bps
ftpd:1.5M/bps

Is this condition the same phenomenon as the thread issue below? Or is it a specification?
I looked at past questions about "speed", but there wasn't much information, so it might be a problem with my settings or the environment.
Speed falling when copying large files #268

Is it possible to change the encryption method?
I looked for the settings but couldn't find it.
This is just an amateur's idea, but I have knowledge about the difference in speed due to different encryption methods during transfer.

ftpd v6.16(code:62) f-droid
copying via: secure ftp
storage type: standard file system
Test phone 1: POCO F5 (Android 13) root

I think I is related but that has to be verified.

Is it possible to change the encryption method?

Should be possible with the usual SSH mechanisms. If I remember correctly you can specify cipher suites client side.

thank you for your reply.
I thought I searched everywhere, but is it possible to change the settings on the app? Please advise how to set it up.

This server provides currently no options for that. You can see e.g. this mozilla link for client side configuration:

I understood that the transfer cipher settings are to be set on both the server and client. Does it mean that you can't change it on the server?
I'm using winscp, what clients do I have that don't have speed issues? Please let me know if you recommend it.

Currently this server cannot change such settings. There are no plans to implement that.

I don't have much experience with windows clients. The other option I know about is FileZilla. Not sure which would be better.
