[rrd-users] Memory usage

[Christian Brechbuehler]

Hello list,

I just started using RRD to write some perl statistics scripts - so
definitely a newbie. When testing the scripts i found a surprising thing:
As soon as I include the RRDs module (just 'use RRDs;', no actual
usage), the virtual memory usage of the scripts goes up from ~20K to
125MB. Is that normal or am I doing something wrong?

Regards
Christian

there are quite a lot of libraries that get loaded with the rrdtool
bindings ...

so that might well be

Any time you `use` a module in Perl, you are loading code into memory. So
yes, memory usage will go up. See the documentation
<http://perldoc.perl.org/functions/use.html> for details.
