Gargoyle Forum

I think you are missing the point of the post, which is the stock firmware can route over 100 Mbps where most (or all) 3rd party firmwares don't get that close. With this particular TL-1043nd router at least. I thought at one point that I posted a link to the openwrt website showing where people were trying to compile firmware for this specific router enabling the gcc processor optimization (again for the specific processor in this specific router) and getting a performance gain. Not sure what happened to that post... annoying.

Best test to try is to flash a plain OpenWRT Backfire 10.03.1 image
on the router and do a basic config, then speed testing.

If the plain Backfire is slower than stock, its overhead added by
OpenWRT itself, and when adding extra software/functions,
such as all the features of Gargoyle, you end up using more
processor power and speed suffers.
