I found one config file by FireEgl@EFNet for eggdrop and it has all these settings.
like
# This will mainly keep any logfiles from being started:
set lowdisk 0
# This will mainly set CPU intensive options to their most conservative settings:
# (this will also (attempt) to renice the pid of Eggdrop to +19.)
set slowcpu 0
maybe it simply will later split into something like this:
if $lowdisk {
set ...
set ...
} else {
set ...
set ...
}
however, we can't tell you about them, these are no builtin eggdrop settings.
PS: he send me the config via PM, its indeed exact that. these settings are later used as if pattern (ex.: if {$slowcpu && !$slownet}) to setup everthing. nice idea at the end with loading the scripts via catch, so the bot wont abort starting on bad scripts.
