Thanks, Gerald. So, just to be clear, what my preload routine in does is the following. Maybe you can confirm that I'm doing 
it right.

if (Apache2::ServerUtil::restart_count() == 1)
    $Embperl::initparam{preloadfiles} = \@preload_files;

The preload_dirs() simply traverses my code tree and calls this for each 

push (@preload_files, {inputfile => $filename, path => $path, import => 
0, input_escmode => 0, options => 16, debug => 0x7fffffff});

Does that look about right? If as you say it's worthwhile in terms of 
memory then I might look at re-enabling it again. I think I disabled it 
originally because it made restarting the server quite slow, but it 
would be useful to have it as an option should I need it.
