Thanks, I'm seeing some results I can't explain, but am hoping you could help. I attached 2 log files:
1) main.log: this is the log from my main computer where my upload speed is around 700KB/s. I'm seeing this speed on a couple machines all on my same local network.
2) vm.log: I installed the IE11/Windows 7 VM from <invalid hyperlink removed by admin> and installed it in VirtualBox on the same machine as above. When I do the transfer there, my upload speed is 2.4MB/s.
Can you see any reason why the VM is faster, or is there more debugging I can do to narrow it down?
Also, if I go in my web browser to <invalid hyperlink removed by admin> from my main computer, I am able to upload the same 100MB file at 10MB/s. Do you see a reason why uploading in a web browser would be that much faster than WinSCP?
The 100MB test file I'm using is from http://speedtest-sfo1.digitalocean.com.
Thanks for your help.
