For example, I just tried to upload 75 MB in 8 files. Before starting the transfer, Windows Task Manager showed 557 MB used. After transferring (actually, only copying) the files, WTM showed 935 MB used. I also tried downloading 17.7 MB. Before starting, WTM showed 548 MB used; after transferring (actually, copying), WTM showed 654 MB used.
Why would transferring 75 MB of files consume 378 MB (935-557) of memory? Why would 17.7 MB of files consume 106 (654-548) MB of memory?
Also, while WinSCP runs, the CPU usage is mostly at 100% utilization. I'm assuming this is related to the excessive outlay of memory resources.
Is there some setting that I can tweak to cause WinSCP to perform more normally?
