I have a VM on Azure, with an SFTP server installed (from nsoftware).
I know SFTP is slower than FTP, but the speed I am getting is abysmal:
Upload: File transfer successful, transferred 10,485,760 bytes in 19 seconds
Download: File transfer successful, transferred 10,485,760 bytes in 99 seconds
The Upload I could live with, but 99 seconds for a 10MB file is unacceptable.
I have tried ramping up the Memory and CPU to very high levels, but the speeds remain unchanged. So it is not clear to me what is throttling the download.
I have check the Performance Monitor, and both CPU and Bandwidth appears ok on both the client and the server.
I don't know what else to try here to speed up the download speed.
SFTP is required by the Trading Partner, so I cannot switch protocols.
