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.
> The performance of uploading and downloading files in SFTP subsystem is very
> poor.

> Key: SSHD-135
> URL: https://issues.apache.org/jira/browse/SSHD-135
> Project: MINA SSHD
> Issue Type: Improvement
> Affects Versions: 0.5.0
> Environment: OS: Windows 7
> JDK:
> java version "1.6.0_26"
> Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
> Java HotSpot(TM) Client VM (build 20.1-b02, mixed mode, sharing)
> Reporter: Liu Tao
>
> When I use FileZilla to upload a big file to the Mina Sftpd, the speed is
> only 30K/S.
> The main reason is that the file is opened and closed frequently when
> SftpSubsystem handles SSH_FXP_WRITE message.
