Since I follow most of the mailing lists for Symfony 2, I have come across Silex a little while ago. However, something new I took from this article was the appserver-in-php project https://github.com/indeyets/appserver-in-php

The blurb on the git project has "The main idea is, that your app, if built for this protocol, will be able to preload resources, preconnect to databases and response to requests really fast.", which seems like it's taking a persistent approach to running PHP apps. How does this deal with the memory leaks etc?

Can anybody knowledgeable weigh in on this with a little detail about what it is, how stable it is, who's using it, how it stacks up to using PHP-FPM in a spawner pool w/ nginx etc... ?

I'm the author of the original post. We use AiP quite a bit in production.

Indeed, memory leaks are a potential issue with persistent PHP. Garbage collection in 5.3 helps a bit, but in general AiP exposes such issues more readily than regular mod_php setups. This doesn't mean memory leaks in your code wouldn't be an issue anyway, it just means you'll notice them a lot more quickly.

AiP workers die when PHP's memory_limit is exceeeded, and AiP will then restart them.

Thank you for your reply. I will have a play with it if I find some free time. It's not the memory leaks in _my_ code I'm so worried about, it's the ones in other people's code :-) e.g. Doctrine used to leak like a sieve and no amount of free()s and unset()s cleared the ORM objects up under some circumstances. Long-running Symfony tasks were a great way to illustrate that. It seems like a sensible approach to auto-restart the processes once memory_limit is exceeded.

how is this anything like express?

See klein (https://github.com/chriso/klein.php) for a real PHP express port..

All of them are inspired by Sinatra. But does Klein do templating, like Silex and ExpressJS both can?

Any reason your tests used HTTP/1.0? It is likely that most of the time is spent in connection establishment and you may not have tested the server.
