---------------------------------
> support asynchronization mode for sftp subsystem
> ------------------------------------------------
>
> Key: SSHD-812
> URL: https://issues.apache.org/jira/browse/SSHD-812
> Project: MINA SSHD
> Issue Type: New Feature
> Affects Versions: 1.7.0
> Environment: java1.8, linux
> Reporter: Zhenliang Su
> Assignee: Goldstein Lyor
> Priority: Major
> Labels: asynchronous, sftp
> Attachments: Main.java, doRead.png
>
>
> I used SSHD as a middleman between client and target sftp server.
> I found that, when filezilla client directly connect to the target sftp server, it transfers fast. When filezilla client connect to the middleman, it transfers slow.
> I analyzed the source code of org.apache.sshd.server.subsystem.sftp.SftpSubsystem#doRead, and I found it behaves like block mode, and client's other SSH_FXP_READ request blocked in the same thread.
>
> my middleman code:
> [^Main.java]
