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