In my opinion you shouldn't try to manage something with a GUI 
over the internet without any encryption. Unless embedded encryption
or thru ssh or VPN. 

VPN's are fast enough, it just depends on the throughput of the data
which you want to send and the VPN links on each endpoint. I think 
using a VPN for management shouldn't slow things down. Emailing 
an attachment of 5 mb and doing management can slow things down
ofcourse.

I personnaly don't prefer doing management of a firewall from any work
station at all instead of a few management stations which you give 
access to the GUI / rulebase.
