The simplest way to gain request-start to request-end speed is to cache using something like akamai.

The official site will have the best most up to date documentation, not that it's a very popular framework IMO.

That is correct.

CodeIgnitor will teach you nothing.

Codelgniter is an abomination and a dying project so forget it. Any of the other 3 are probably worthwhile though I don't hear much about Cake these days (but that is likely just the circles I hang in). As for where to start. This question gets asked all the time and the answer is always the same. Try them all and see. If I were in your position I would spend a weekend with each, and then decide. They are all very capable, so it's just personal opinions as to which one you like best.

Your code is unreadable.

It is. I use it on a daily basis with a few large Symfony2 based applications. It's a great tool. http://thorpesystems.com/blog/debugging-php-in-vim I'm pretty interested in taking a look at http://phpdbg.com one of these days too as it ships with PHP5.6.

The second question in particular assumes you are talking about client side (executed in the browser) javascript. Server side javascript is becoming more and more popular these days and is capable of making use of many different database systems.

vim for Windows? Yuk.

We do not delete accounts. If you don't want it, don't use it, simple.

2 & 3 will never happen using vim's autocompletion. And 1, well, vim gets its context from a few different locations depending on the keystroke you use to start completion. Generally, I only ever use the context of the current buffer. This meens variables will only be completed if they already exist in the current buffer. Not that I use completion often anyway.

Not at all. That's why I said I rarely use it.

vim's code completion is the best (quickest and most flexible) Ive used, not that I use it often.

Silex (http://silex.sensiolabs.org) is an awesome micro-framework built on the shoulders of Symfony (another great though full stack framework).

This resonates with me more than anything else. http://blog.sanctum.geek.nz/series/unix-as-ide/
