#1278: Very high memory usage during large SFTP download

     Type:  defect   |      Status:  new              
 Priority:  high     |   Milestone:  2.8.1            
Component:  core     |     Version:  2.8              
 Severity:  major    |    Keywords:  memory usage sftp
---------------------+------------------------------------------------------
 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!
