I know I'm answering Mike and not Andreas but here's one user's take on the perl performance question. I can say that while a 15-30% penalty sounds like a lot, it certainly depends on at least a few other factors. For instance, the difference between running Interchange on something state of the art verses an older, slower machine would probably be considerably more than 30%. So, comparing unthreaded perl on my old 2.4GHz P4 to threaded perl on one of the newer, faster processors the threaded perl would probably be faster. If responsiveness was acceptable on the old machine with untreaded perl, I don't see how it would be unacceptable with threaded perl on a faster machine. Sure, for heavy loads you will want both and if I were building a site that expected lots of traffic, it would justify the extra cost of the hardware and the extra time to set up and maintain the system. This is just a guess but many Interchange sites probably rarely see two concurrent users and for them it isn't going to matter as much. Also, saving 15-30% in speed doesn't matter as much if things are already fast enough. That is, if a process adds a half second or two to a page being loaded, it's not going to be noticed by most people. The benefits to using the default Perl, while also modest, are that a machine can be set up and maintained that much more easily. Either way, it's not going to be a deal breaker. In my opinion, having the choice is a Good Thing (TM). If I spent the time to get used to Gentoo, it would probably be worth the effort but I've been doing things "The Red Hat Way" for so long, it's hard to switch. -- Henry _______________________________________________ interchange-users mailing list suppressed http://www.icdevgroup.org/mailman/listinfo/interchange-users
