Old description:
> CyberDuck 2.5.2 uses lots of CPU when downloading many small files. The
> output from sample indicates that all the time is being spent in a
> routine called Java_ch_cyberduck_core_Local_setIconFromFile which calling
> into routines doing all sorts of JPEG processing! (I'm downloading a
> directory of several thousand small files via sftp.)

New description:
CyberDuck 2.5.2 uses lots of CPU when downloading many small files. The
output from sample indicates that all the time is being spent in a routine
called Java_ch_cyberduck_core_Local_setIconFromFile which calling into
routines doing all sorts of JPEG processing! (I'm downloading a directory
of several thousand small files via sftp.)
