[jira] [Commented] (SSHD-1049) comparison between SftpClient and
sftp comand in Windows10
[ https://issues.apache.org/jira/browse/SSHD-1049?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17170584#comment-17170584 ]
Lyor Goldstein commented on SSHD-1049:
--------------------------------------
In a related issue - I was wondering how does SCP compare. I always thought that SCP is more suitable for transferring large files since it involves less traffic overhead. Can you do a comparison of it as well ?

> 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
> Priority: Minor
>
> # 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.
