We have Azure (Microsoft cloud), we have installed winscp to upload and download files to SFTP server but performance is too much low, it takes more than enough time to upload and download 50-100 MB files. After discussing with SFTP server team, they have pointed that server does not have any performance issue as other clients are not facing this issue.

a) We need to test performance of SFTP client (WinSCP) on our Azure (Microsoft cloud) VM. Winscp connects to SFTP server and it uploads/downloads files to/from it.

b) Can performance of sftp server be measured at our end? We have to be sure that all is well at server's end because our client is also installed on cloud.

What should I do to achieve this? I found sftp load testing can be done using jmeter but I am not sure how it is going to measure performance of winscp client.

Please suggest.

Note : we use ppk and asc (pgp encrypted) file to connect to sftp server.

You could run a performance daemon on the server and look at the output after the fact. You say you client is also in the cloud. Is that a client machine or a business customer? ISP connections can have upload and download speeds. Perhaps that is an issue. Could you give us some actual scenarios?

Is the Azure server running Windows? I presume that it is, since WinSCP is a Windows application.

Is the Windows Task Manager available? The Windows 10 version does a good job of reporting loads by application.

I'm more inclined to suspect a bandwidth limitation, however. I don't see much load on my Windows client when running WinSCP. What are the bandwidth specifications for the cloud server?

We have account on azure server, we connect to windows using RDP where we have installed winscp. We open this software and connect to SFTP server which is on another cloud. We download files on azure cloud, work on them and upload again on same server using same client. This is our scenario what we follow.
We tried to connect azure from different network where no firewall implemented but still we are facing same issue.

Yes windows task manager is available but we have windows 8 server. We do not have bandwidth specifications.

Can you please suggest how should I do load testing for this scenario. I haven't done load testing for SFTP server before. I have done for web applications only. Your suggestion will be great help for me.

Thank You

Hello sir,

This is my issue. Why are you hijacking my thread? You do not know nothing about my configuration. It is windows 10 server. If you have similar issue which can't be possible but still you have, kindly create your own thread.
