Doing this on the fly (for mod_perl) would be a big drawback in performance. Maybe there should be some kind of precompiling. Smart templaters cache templates and results. The REALLY smart ones compile the templates into perl code and hold them as a reference to an anonymous sub. The problem with many templating systems is the fact that they invent a new language like "td$variable/td" which is usually not displayable in the Browser so that the designer and the programmer must work tightly.

So we doubled the memory to 128 Meg and over the next 10 minutes of using the site (having restarted the server) we watched as all the extra memory was used up and it went back into swap! So here are some questions: 1. What is a 'ball-park' figure for mod_perl memory requirements? http://perl.apache.org/guide 2. What is the entry level spec for a mod_perl/Apache/Linux server? http://perl.apache.org/guide 3. Should I reduce the number of Apache child processes (currently 10) ... to reduce memory consumption? http://perl.apache.org/guide 4. Will mod_perl always ramp up its memory consumption to whatever is available? http://perl.apache.org/guide 5. Should we throw money at the problem and just buy more memory? http://perl.apache.org/guide 6. I have not been able to get Apache::DBI to work. Will Apache::DBI significantly reduce memory consumption (every script opens a DB handle for session checking)? Put it _first_ in startup.pl. Any help, and war stories that you may have would be much appreciated ... http://perl.apache.org/guide ;-) -- Dave Hodgkinson, http://www.hodgkinson.org Editor-in-chief, The Highway Star http://www.deep-purple.com Apache, mod_perl, MySQL, Sybase hired gun for, well, hire -

Nah, not good, you still have to budget a fair few meg per mod_perl site. Yea, that's the problem as I see it..., modperl processes can be _huge_, so you need a finite way to control with an absolute hand the size of those processes. Limiting by number of threads on that users own dinky little apache seemed a plausible way to go. At least apache and mod_perl are shared. But every user will end up with a CGI.pm or somesuch in this scenario. Plus, I've fixated on Apache::Registry type stuff, not dinky little per-site bits of code. -- Dave Hodgkinson, http://www.hodgkinson.org Editor-in-chief, The Highway Star http://www.deep-purple.com Apache, mod_perl, MySQL, Sybase hired gun for, well, hire -
Re: mod_perl and FastCGI, again
"Kenneth Lee" [EMAIL PROTECTED] writes: Hi there, Not performance. Not preference. The question is, will mod_fastcgi and mod_perl conflict when both are compiled into Apache? Theoretically not I think. And what would the consequences be? Please comment. As long as you keep the paths or suffixes they use distinct, then no. Um. However, there's no reason, I think, that you couldn't wrap a few handlers before and after the execution of a FastCGI script. So, yes, they _could_ possibly interfere, but in a controlled way :-) -- Dave Hodgkinson, http://www.hodgkinson.org Editor-in-chief, The Highway Star http://www.deep-purple.com Apache, mod_perl, MySQL, Sybase hired gun for, well, hire -

So if startup.pl contains: use CGI ; use DBI ; use My::Application ; Then there's no gain? Of course there is! I'm talking about a completely diffent thing. Let me repeat this again. Spawning of the child process has almost nothing to do with code. When the process is spawned it's memory pages are _shared_ with parents, and the child process has almost no pages on its own. So, we have: - initial apache startup: compile stuff that's in startup.pl - the Apache::Registry script gets run: compile the Apache::Registry script[0] memory pages get dirtied as we touch various bits of memory connect to any resources[1] [0] Which, ideally is just a stub. [1] Subsequently these connections can be cached, say in code that knows about Apache::Registry, or for free with Apache::DBI. Are we nearer now? I was having a block about pre-forking threads and running a script for the first time, not trying to be deliberately obtuse. -- Dave Hodgkinson, http://www.hodgkinson.org Editor-in-chief, The Highway Star http://www.deep-purple.com Apache, mod_perl, MySQL, Sybase hired gun for, well, hire -

MinFree is set to 2 .. as 12 becomes 11 becomes 10 becomes 9, my backend is getting less and less powerful and more and more swamped. When Apache does wakeup and spawn a new child, it takes many seconds to interpret all the (large amount) of perl code and modules that are not in the parent... up to 10 seconds now since its only getting a fraction of the box.. this gives the unlucky user a dead browser. Worse, the remaining alive servers are dieing faster now as they handle more and more of the load, and rush towards 500 to contribute to the same traffic jam of booting children. I'd worry about the cranking up time. It sounds like you need to preload your modules in the parent process.

It makes no difference to the spawning time, since all the code is shared at the beginning. Isn't that what I said?! :-) If you take a large script, throw it at Apache::Registry, then you'll be compiling the script every time the a diaghter respawns. If you have your script largely preloaded when Apache starts spawning daughters, then you don't have that overhead. When a new process is spawn 99.9% of the memory pages are shared with parent. When the pages are getting dirty (some data modified) a copy-on-write happen which slows things down, but it has nothing to do with child spawning. The slowdown happens during the request's processing. If you don't preload your code, the first time a script need it the delay of load and compilation will happen and there will be less memory shared. -- Dave Hodgkinson, http://www.hodgkinson.org Editor-in-chief, The Highway Star http://www.deep-purple.com Apache, mod_perl, MySQL, Sybase hired gun for, well, hire -

The advanced perl programming book has a nice section on OO. But, learning OO in a Java or C++ context would probably be the best way to start. The Conway book is excellent. I've made several runs at C++ and Java at various times but I've never been involved in OO development that went beyond the the "toy" stage. This book taught me as much about how perl works as how to apply it to OO. That said, I've used the Conway book as the bible for my latest development and in terms of all the OO Good Things the book offered good examples and good code templates.

Job: mod_perl developer in London
The guys I've been working with for the last couple of weeks need a contractor to start moving their more heavily hit scripts to mod_perl. It's likely to be at least a three month gig, but they're looking for someone with real world mod_perl battlefield experience. Then some general code analysis and re-engineering. They're nice guys in nice offices in Farringdon. Plus there's a Fuller's pub right next door. Better than reasonable rates too. Mail me if you're interested...
