问题 I am using the Renci SSH.NET package version 2016. I am downloading files from an external server. I usually can download about one file every 6 seconds which is bad when you have thousands of files. I recently tried to change the foreach loops to Parallel.ForEach . Doing that changed the files downloaded times to 1.5 seconds. Except when I checked the files they all had 0 KB's so it did not download anything. Is there anything wrong with the parallel loop? I am new to C# and trying to

问题 When uploading 100 files of 100 bytes each with SFTP, it takes 17 seconds here ( after the connection is established, I don't even count the initial connection time). This means it's 17 seconds to transfer 10 KB only, i.e. 0.59 KB/sec! I know that sending SSH commands to open , write , close , etc. probably creates a big overhead, but still, is there a way to speed up the process when sending many small files with SFTP? Or a special mode in paramiko / pysftp to keep all the writes operations

问题 I have to run a few commands of WinSCP from a Python class using subprocess. The goal is to connect a local Windows machine and a Windows server with no FTP installed and download some files. This is what I tried python proc = subprocess.Popen(['WinSCP.exe', '/console', '/WAIT', user:password@ip:folder , '/WAIT','get' ,'*.txt'], shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE) With this I get it to open the WinSCP console and connect to the server, but it doesn't execute the get
