Easy. Just make a special version of dmd that lexes only, and time it.
I made a lexing-only version of dmd at
https://github.com/edmccard/dmd/tree/lexonly
by stripping non-lexer-related code from mars.c, and adding a lexModule
function that is called instead of Module::parse.. There's no
benchmarking code yet; it basically just does
while (token.value != TOKeof) nextToken();
for each D source file passed on the command line.

Walter mentioned an easier way - without "forking" dmd - should be
better an integral part of the ongoing development maybe under a tools
or benchmark section?

->Look in doc.c at highlightCode2() for how to call the lexer by itself.
