To get the best performance from Embperl, it is necessary to restrict
logging to a minimum. You can drastically slow down Embperl if you
enable all logging options. (This is why `make test' takes a while to
run.) You should never enable dbgFlushOutput or dbgFlushLog
in a production environment. More debugging
options are useful for development where it doesn't matter if the
request takes a little bit longer, but on a heavily-loaded server they
should be disabled.
Preloading of page can save memory, because preloaded page can be
shared between child processes. See perldoc Config
for more details.
