I get ratios 8/14 and 8/30 on the average when comparing 3.15p with 3.4.5
(GNAT GPL 2005) and 3.15p with a 4.1 FSF GNAT from Ausgust this year,
compiling a recursive descent parser.

Part of the speed difference is probably due to --enable-checking
in non-release compilers (the 4.1 case).

Have you compared execution speeds of the executables produced?
