Conky is generally very good on resources. However, certain objects in
Conky are harder on resources then others. In particular, the $tail,
$top, and $graph objects are quite costly in comparison to the rest of Conky.
$top, $font, and $graph objects are quite costly in comparison to
the rest of Conky.
If you do use them, please do not complain about memory or CPU usage,
unless you think something is going seriously wrong (mem leak, et cetera).
