Latency Problems

I'm using smart FTP over a satellite connection, with a large number of small files. The latency problems are causing the FTP connection to hang. Can I change any settings to make the transfer allow more time for acknowledgements and stop it hanging. On a related note, is it more or less likely to work with high or low simultaneous threads?

You can try changing the Server Timeout setting if that's what you mean.

Tools > Settings > Connection > Server Timeout.
