Come to think of it, only DosBox AGA and NetSurf AGA need more than 130 MIPS!

Netsurf isn't that bad at 100MIPS :-) What makes it appear slower than say ibrowse is the 68k version appears to try and load the entire page first before displaying it.
I use netsurf now and then with RTG quite useable. Of course faster is always better.
