Hi Neil, Embperl is not working with threaded mpm.
Preloading all your perl code saves a lot of memory due to code sharing. The main issue is, that you have to make sure, not to open any file or database connection or similar in the preload code, because that will be shared too, which does not work Gerald -----Ursprüngliche Nachricht----- Von: Neil Gunton [mailto:n...@nilspace.com] Gesendet: Sonntag, 25.

The prefork does seem to limit somewhat the number of clients I can have on my server, presumably due to the memory footprint (no shared code between processes?). It's been a while since I played with that stuff, so I've probably forgotten some things that I should have written down "way back when" I was developing the core website config in the early 2000's. Like, exactly how shared is the memory for my Perl code between Apache's preforked processes? I don't currently explicitly preload (Execute) all of my Embperl code at startup, even though I have a switch for that in my startup.pl, and it's been so long now (> 10 years) that I don't remember why I disabled it. I do seem to remember that if you execute all your files in startup.pl then it's shared at first, but then over time that becomes more fragmented (non-shared)? Sorry to be so vague, basically the way mod_perl/Embperl works with respect to how code gets shared (or not) between processes has always been a bit murky to me, so any tips would be appreciated. Also, of course, whether event/worker is a thing I should be looking at for Embperl at all. Thanks!
