Hi!
Also, with both languages, you will have an IO bottleneck.
Yes IO is really the bottleneck I have seen that.
You can greatly reduce IO wait if you write the data to a different disk
than you read from. Speed up things even more, consider using a hardware
RAID

m To perform the test, I'd just use 'time':
that is a very poor way to compare speed. it doesn't account for perl's
startup time vs running time.

m int a = 1 + 1;

How about the files parsing with huge size (about 1T of each day)?
The basic logic is:

look for special info (like IP, request url, session_id, datetime etc).
count for them and write the result into a database
