I thought Rainer Bawidamann implemented this a month or two back, but
I might be mistaken as I can't find nothing about it on the 14all.cgi
Anyway, I tried this approach for my config files, ranging from almost
nothing to 500kB. The performance gain is considerable, and on a 440MHz
T1 a full MRTG-like dynamic page (9 separate CGI-invocations) for a tar-
get in a 450kB configuration file is displayed in 3-4 seconds. I assume
mod_perl would speed this up another 50% or so when I get around to it.
