Just curious how fast is gzip?

I know that it will lower the size of the transfered data but will it make it faster too? Or will it make everything even slower because the compression takes some CPU power?

Also I know two different methodes to use gzip: internal and external

open(GZIP, "| gzip -f");
print GZIP $output;
close(GZIP);
 

and

require Compress::Zlib;
print Compress::Zlib::memGzip($output);
 

what is faster/takes more cpu power?

huh? I didn't get that... what is faster than gzip?

oh ok

I'll enable gzip for this board here then... lets see if it makes a difference...

Most modern computers (and even not-so-modern) are I/O bound. They can process data much faster than they can read and write it to/from storage. This means you have boku CPU cycles to spare between I/O cycles and you may as well use them to reduce the total amount of data you need to transfer.

Where I work we regularly work with data sets over 100meg, some approaching several gig, so we need to compress them on-the-fly as they are created in order to keep the disk transfer time down.
