Hello,

on my machine SFTP Server upload speed is approx 1MB/22s (download about 20 times faster). The upload speed is controlled by OnWriteFile event which is fired approximately once a second for amout of 32kB data. My question is if it is possible to increase upload speed somehow (to incerease frequency of this event or buffer size).

Thx

The OnWriteFile event is fired when the corresponding data packet is received from client. I.e., packet size (32kB in your case) depends on implementation details of SFTP client software.

BTW, are you using evaluation or 'real-world' key?

Yes, I am using valid key. The client I am using is WinSCP 3.8.2.

Your sample client is about 0,64MB/s for both upload and download. Ok.

Thank you for letting us know.

We will investigate the reasons for such a slow speed of WinSCP and try to optimize the server (if possible) for it.
