Tried Slim... Can grab off my server @ over 220 KB\s to the ipaq filestore. To SD it maxed around 90 KB/s.
Also tried Resco Explorers FTP plugin... It was slow... 32 KB/s max to filestore. 16 KB/s to SD.
Looks like speeds are very protocol dependant.
When I use Resco Explorer and a mapped Network drive I download @ 264 KB/s to the SD and the same to the file store...
FTP needs an overhaul.
Hardware is a 4150 and a 1 GB Lexar 32x.
