Guillaume Nodet commented on SSHD-1044:
---------------------------------------
The performance boost can very between x2 to x100 depending on the latency of
the network. There's no config to trigger, however, you need to use the
correct API and relinquish control to SFTP: you need to ensure that you're
using the {{SftpOutputStreamAsync}} output stream to upload your file and not
the {{SftpClient.openRemoteFileChannel}} method, or better simply use the
{{FileSystem}} api from the JDK.
> How to improve sftp transfer speed
> ----------------------------------
>
> Key: SSHD-1044
> URL: https://issues.apache.org/jira/browse/SSHD-1044
> Project: MINA SSHD
> Issue Type: Question
> Reporter: barry-gq
> Assignee: Guillaume Nodet
> Priority: Blocker
>
> *Phenomenon*:
> In my project, I used mina sftp version 2.4.0. When my project created
> a sshdServer and connected to a linux device using the sftp protocol, the
> speed was very slow when performing file transfer (upload) operations, About
> one-tenth the speed of connecting the same device with filezilla and
> uploading the same file
> *Question：*
> Is there any configuration in mina sftp 2.4.0 to increase the speed of
> file transfer
>
> *I look forward to your reply, thank you！*
