[jira] [Commented] (SSHD-135) The performance of uploading and downloading files in SFTP subsystem is very poor.

Posted by "Bobby Powers (JIRA)" <ji...@apache.org>.

Bobby Powers commented on SSHD-135:
-----------------------------------

interesting.  We could try creating a single outputstream when SSH_FXP_OPEN is opened with a write flag, closing it on SSH_FXP_CLOSE.  Would you be interested in contributing a patch?  If not I'll take a stab at this this weekend.
