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

Hi Raymond,
Thanks for the info.
Again, my name is "Xiaolan Foo", "xiao" means "small", "lan" means "orchid".
So the union of "xiaolan" is my first name, and "foo" is my last name.:-)

Thanks all.
How about the files parsing with huge size (about 1T of each day)?
The basic logic is:
reach each line of every file (many files, each is gziped)
look for special info (like IP, request url, session_id, datetime etc).
count for them and write the result into a database

that is a very poor way to compare speed. it doesn't account for perl's
startup time vs running time.

Hello,
Maybe it's not so suitable to ask this here.
But is there a good way (code sample?) to implement a speed test
between Perl and C?
For a project which handles lots of data we want to know how slower

Thanks.
