To transfer files from my Android phone to Ubuntu, I use an app that creates a FTP server on the phone.
Copying files to Ubuntu 12.04 (same with 12.10) I get up to 260 KB/s. Copying files to Windows 7 I get up to 1050 KB/s.
I am currently on a fresh install of 12.10 with barely anything installed with the same results. I have tested with both a Galaxy S3 and HTC Desire HD with identical results. I have tested about 5 apps with the same results.
Why is it slow on Ubuntu?
