             Summary: comparison between SftpClient and sftp comand in Windows10
                 Key: SSHD-1049
                 URL: https://issues.apache.org/jira/browse/SSHD-1049
             Project: MINA SSHD
          Issue Type: Question
    Affects Versions: 2.5.1
         Environment: windows10
centos 7
            Reporter: Tsing Wang


# try with the latest version 2.5.1
 # comparison test

 ## method 1: using cmd.exe in windows, sftp username@host, then put large file, it displays about 70-80M/s
 ## method 2: using the performance test class in github (SftpPerformanceTest), cal t1-t0. for 100MB file, it takes about 5s to finish. So the rate will close to 20M/s - 30M/s,  it do improve with old one( speed up about 3 times).

the test result's throughput is about 1/3 compared with sftp command, so I am curious about what's limit for sftpclient.

 

Also I setup a simple sshd server in target linux machine, the upload rate is also about 1/3. I wonder what's expect for sftp performance.
