So your server is like an SFTP proxy (it doesn't use the local file system, but connects again to some other server and forwards stuff). Basically you have ``` SFTP Client ---> SFTP Server A ---> SFTP Client (on A) ---> SFTP server "targetIP" ``` I'm aware of the performance problems with this. SFTP is not well suited for such kind of proxying; you're probably better off forwarding SFTP requests directly. (Basically, don't use a filesystem but a special purpose SftpSubsystem that forwards requests directly, without ever going to the filesystem. The filesystem is just an awkward detour for such a use case.) And no, the "same processing as in SftpOutputStreamAsync" won't help. The server A only sees a series of write requests; it doesn't know that these writes are contiguous or even in sequence. I do wonder about your claim that it was "1-2 times slower than OpenSSH". How do you do this kind of SFTP proxying with OpenSSH on server A? It _is_ 1-2 times slower than uploading the file directly to the "targetIP" server, whether that targetIP server runs OpenSSH or Apache MINA sshd. -- This is an automated message from the Apache Git Service.
