Default slow download speed via sftp

hello!

getting slow download speeds via sftp...

Key exchange: curve25519-sha256@libssh.org. Session encryption: chacha20-poly1305@openssh.com, MAC: <implicit>, compression: zlib@openssh.com.
Connection established with OpenSSH_7.2p2 Ubuntu-4ubuntu2.1 (SFTP v3)

getting about 2mb/sec down, while filezilla does about 12mb/sec...

hoping for a fix or is there an issue on my end...?

kind regards

Are you using the same ciphers and compression settings in filezilla?

oh - I thought it would get handled by default...

filezilla:
Trace: Server supports delayed compression; will try this later

I switched in flashfxp... prolly I'm choosing still wrong ones...

[09:00:01] [R] Key exchange: curve25519-sha256@libssh.org. Session encryption: aes256-gcm@openssh.com, MAC: <implicit>, compression: zlib@openssh.com.

as I'm still stuck @2mb/sec...

I am not seeing anything that would explain your slow speeds (your results are not typical)

What is your speed if you turn off the compression setting? Site Manager > SFTP tab > uncheck [ ] Use Compression

I refactored some of the code in the SFTP download routine, this eliminated a potential cpu/memory bottleneck and adjusted the default SFTP block and packet sizes.

This seems to improve performance 5~20% depending on several factors.

Please try the latest release and let me know.
