My main concern is just the response time of the servers. Mostly connecting via SFTP annoys me because it can sometimes take up to 10 seconds just to refresh the directory listing, another 3 seconds to compare file timestamps, and then up to 10 more seconds to overwrite the ~3kb file. So that's approximately 23 seconds per file that I'm uploading, which in my opinion is horribly horribly slow for such small files. I know it's not my internet connection, because speed tests show I have, on average, a 5mbps down/700kbps up connection. Other websites and FTP servers are very responsive. Even doing site speed tests on the files on my website can sometimes take up to 5 seconds to server, and those sites use internet connections that are on orders of magnitude better than mine. So I believe I will be submitting a request here soon if things don't shape up.
