title: Apache SSHD client performance
body: <p>I have an application using apache SSHD to send files via sftp (with the SftpClient class). I have noticed that the performance was very poor and I made a simple test comparing apache SSHD with Jsch, which gives much better results (seven times faster!) comparable with the openssh implementation.</p>
  
  <p>Even though the performance can be partly improved (~30%) by changing the buffer size, for example, I haven't been able to match Jsch's performance by a long shot.</p>
  
  <p>Has anybody noticed similar performance issues using apache SSHD as a client?</p>
  
  <p>Do you have any suggestions to tune the performance, besides the buffer size?</p>
