I can't really offer much, sorry. The java code generator is not made
for speed.

Hi everybody,
I am trying to figure out what could be the best solution to tokenize
really big files like 1GB or 1TB.
I just came across Ragel and I wrote a really dummy benchmark.
You can see it here: http://pastebin.com/7rdyBWNS
It does nothing except going through the file looking for the next 'a'.
On my laptop this code need 4586ms to go through 100MB.
I would like to ask you all if I made any mistakes on the parser (it's
my first time with ragel) and if you know any way to improve its
performance.
ps: Just as comparison java is able to "just read" that file in 700ms
while a stupid but hand-made parser can do it's job in 2300ms
Thanks for in advance.
