Cyberduck uses in excess of 1GB of memory while performing a 15GB SFTP download. This is using version 2.8 on OS X 10.4.

I canceled the transfer at one point and then resumed it. The memory usage is decent while Cyberduck is listing the files, but grows past 1GB after listing 12.5GB of the files (12.5GB was already transferred). The transfer starts, but goes very slowly (i.e. 30KB/S when it should be capable of in excess of 1MB/s), persumeably because there's only about 26MB of free memory left on the machine.

The machine where Cyberduck is running is a MBP (newest generation) with 2GB RAM. And the server it is downloading from is a Gentoo Linux server running up-to-date versions of OpenSSH servers.

Please let me know if you need any more information. Thanks!
