not a great app

I bought this app for exchanging large files (results of simulations) between Mac and linux clusters. Unfortunately, it is quite slow. The subdirectroies donot update quickly, and I have to refresh a few times (because TRANSMIT does not respond) the host folders, to be able to transfer the files back to my Mac. I was hoping that it would be as good as SSH secure file transfer, at least for the data transfer, but unfortunately it is not.
