---------------------------------
Summary: 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
Attachments: Main.java
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:
