Description

mod_compress can really make things faster but its performance is very compromised if the CPU is too busy with other tasks. So, this mod should be able to be auto-suspended if loadavg (/proc/loadavg) gets too high, reaching a value set in lighttpd.conf with a grace period.

Doing so, in any scenario, mod_compress will only boost performance, not making it worse.

Simple/proposed patch for adding config option "compress.max-load-avg", and checking "/proc/loadavg" every 10 seconds.

Known 'flaw': mod_compress will NOT deliver cached already compressed files if load is considered too high, but will deliver the uncompressed file (as if mod_compress was disabled).
