> Reporter: Sreedhar J
> Priority: Major
>
> as part of my performance test, I am sending 180 concurrent requests to Apache SFTP Server, but I can got the test completed. around 10 to 15 requests gets timed out. Are there any known tuning properties on the SSHD/SFTP Server which increases the concurrent connecttion request processing.
> Also, Anyone has some data around max concurrent connections?
