You have to be careful about what is realistic though... Trying some
homebrew DES-encryption code with cc -O4 vs. gcc 1.37.1, on a Sparcstation
under both 4.0.3 and 4.1, Sun cc won each time by about 10% on both of two
DES-related operations.  TeX is certainly much bigger, but both are "real"
applications.
