One more thing:
Freenode has given me about ~20 slots to work with on this demo. If you can't connect, try another network, like `irc.rizon.net` or something.
While I haven't implemented the logging yet, I'm thinking about storing them in the JSON-format. Messages are already stored as JavaScript object, so I think this is my best option. And exporting them as .txt on demand, shouldn't be a problem either.
I've been thinking about storing the logs in .txt-files (with the option to turn this feature on/off). This way, I could let the user download the logs directly via the browser.
It's really stable (been using it for weeks without restarting) and I've even implemented a mobile interface: https://db.tt/fYTswBwO
You'll find the install instructions in the README (or just `npm install shout`). No configuration required. Should take under a minute to get it running if you already have NPM.
It's open source. Feel free to try it, browse the code and leave some feedback. If you want to work with me, it's open for contributions!
I don't think it's fair to say that Drupal is faster than Wordpress by just looking at the req/sec.
According to https://wiki.php.net/phpng, they benchmarked against Wordpress 3.6 (the current version is 3.9). I couldn't find anything about the Drupal benchmark, but it could be a simple "Hello world" for all we know.
