In a nutshell, it boils down to this: project/ + apache/ + bin/ That requires binary compatibility, though. I have a similar setup, but the perl and Apache are built separately on the target machine since my machines are linux and the production machine is Solaris. No, you don't need binary compatibility. You just need to design your system right and use the right tools. :-) With Perforce - http://www.perforce.com/ - you can map different directories in the repository to directories on the client with client views. I have used that (Graham Barr came up with it there) so we could keep the binaries version controlled too. It's great. There we had all of our application software (including perl, apache, etc) distributed with perforce. With CVS or Subversion you could do something similar by setting up branches right or having a few symlinks. We had separate installations around the world serving different clients. Before we migrated from CVS to perforce we had a cvs tag for each installation, so rolling a new release was just o) make a new release number (r345), tag the files with that o) move the installation tag (LosAngeles_Production or QA or whatever) to the new release tag (r345). o) tell the servers to upgrade and restart the application. Perforce provides some features that makes it a bit neater, so the implementation was different but the concept the same. It worked (works actually) great. At another place we have a script to tag the files with a build number and then roll some tar balls. The tar balls then go to QA server and then to the production servers. There all the code is living on shared NFS servers, so rolling it out is just putting the code there and restarting the servers. Perl, Apache, etc are installed with rpms there. For a big project I like installing everything in /home/[project]/ - including perl, apache, mod_perl, ... - and having the whole directory version controlled. On the perl.org we have a bunch of smaller projects. There we use a shared /home/perl/ installation that gets distributed to the servers we use for production and for development. It has perl 5.8, various versions of Apache and other goodies. Each project (in /home/[project]/) then just reference that installation. Making it easy to setup a development environment on your own box is really really nice. On bigger projects I often even have several development environments installed at the same time, so I easily can work on different sub project or test different branches at the same time.

Often overlooked for caching is a simple file based cache. Here's a story about that: A while ago Graham Barr and I spend some time going through a number of iterations for a self cleaning cache system. It would take lots of writes and fewer reads. In each cache entry a number of integers would be stored. Just storing the last thousand entries would be enough. We tried quite a few different approaches; the most noteworthy was a system of semaphores to control access to a number of slots in a BerkeleyDB. That should be pretty fast, right? It got a bit complicated as our systems didn't support that many semaphores, so we had to come up with a system for sharing the semaphores across multiple slots in the database. Designing and writing this implementation took a few days. It was really cool. Anyway, after fixing that and a few deadlocks we were benchmarking away. The system was so clever. We thought it was simple and neat. Okay, neat at least. And it was really slow. Slow. (~200 writes a second on a 400MHz Pentium II if I recall correctly). First we suspected we did something wrong with the semaphores, but further benchmarking showed that the BerkeleyDB just wasn't that fast for writing. 30 minutes thinking and 30 minutes typing code later we had a prototype for a simple filebased system. Now using good old Fcntl to control access to simple flat files. (Data serialized with pack(N*, ...); I don't think anything beats pack and unpack for serializing data). The expiration went into the data and purging the cache was a simple cronjob to find files older than a few minutes and deleting them. The performance? I don't remember the exact figure, but it was at least several times faster than the BerkeleyDB system. And *much* simpler.

Our quick solution was first to reduce some the number of Mod_perls that we had running, using the proxy-front-end/modperl-back-end technique, You should always do that. :-) and then supplemented that by adding another Gig of RAM to the machine. And yes, once you've lost the shared memory, there isn't a way to get it back as shared again. And yes, I've also seen that when this happens that it could full well take the whole server right down the toilet with it (as then your ~800MB of shared memory becomes ~800MB of _physical_ memory needed, and that could throw the box into swap city). I forwarded this mail to one of the CitySearch sysadmins who had told about seeing this. He is seeing the same thing (using kernel 2.4.17), except that if he disables swap then the processes will get back to reporting more shared memory. So maybe it's really just GTop or the kernel reporting swapped stuff in an odd way.

The most effective changes are almost never simple coding changes like the one you showed, but rather large things like using qmail-inject instead of SMTP, caching a slow database query or method call, or changing your architecture to reduce the number of network accesses or inter-process communications. It all depends on what kind of application do you have. If you code is CPU-bound these seemingly insignificant optimizations can have a very significant influence on the overall service performance. Of course if you app, is IO-bound or depends with some external component, than your argumentation applies. Eh, any real system will be a combination. Sure; when everything works then it's worth finding the CPU intensive places and fix them up, but for the most part the system design is far far more important than any code optimiziation you can ever do. My usual rhetorics: Your average code optimization will gain you at most a few percent performance gain. A better design can often make things 10 times faster and use only a fraction of your memory. On the other hand how often do you get a chance to profile your code and see how to improve its speed in the real world. Managers never plan for debugging period, not talking about optimizations periods. And while premature optimizations are usually evil, as they will bait you later, knowing the differences between coding styles does help in a long run and I don't consider these as premature optimizations. If you don't waste time profiling every little snippet of code you might have more time to fix the real bottlenecks in the end. ;-) [...] All I want to say is that there is no one-fits-all solution in Perl, because of TIMTOWTDI, so you can learn a lot from running benchmarks and picking your favorite coding style and change it as the language evolves. But you shouldn't blindly apply the outcomes of the benchmarks without running your own benchmarks. Amen.

At ValueClick we only have a few BerkeleyDBs that are in the request loop for 99% of the traffic; everything else is in fairly efficient in-memory data structures. So there we do of course care about the tiny small optimiziations because there's a direct correlation between saved CPU cycles and request capacity. However, it's only that way because we made a good design for the application in the first place. :-) (And for all the other code we rarely care about using a few more CPU cycles if it is easier/cleaner/more flexible/comes to mind first).

RewriteCond %{HTTP_HOST} ^www\$

(I put the above in the reverse proxy to shield the real thing

get a mail for each 404; it got really old really fast with this
Nimda crap).
Of course it doesn't work if you ever access the host as www

Currently, we only have one instance of Apache running, and I've noticed that the httpd child processes are quite large (up to 32megs!). We've upgraded the RAM on our server twice and now we're at 512, but it seems to be using all of that without a problem. Are these httpd processes so large because they include copies of both perl scripts? Would it be more efficient to set up two instances of Apache, one for each site/IP, and that way each child httpd would only contain one of the two perl scripts?
