Site performance optimization

I'm trying to improve performance on my website. I used a performance analysis site and it says I should move static content to a cookieless domain. What do cookies have to do with performance?

And any other tips for increasing the speed of a website? I'm thinking I should do some sort of in-memory caching, like Redis or memcached or something? But my hosting has pretty limited RAM.

Should I just go with some free AWS tier for like Elasticache or some shit instead of having everything on-disk on my main hosting?

Quit with the stupid ``web development isn't real programming'' bullshit.
Web development is more useful and also more complicated than making metaprogrammable hello world bullshit in Lisp.

The reason people look down on web dev is because it's full of cargo cult programmers who throw one-size-fits-all buzzword solutions at straightforward problems they're just incapable of analysing. I'm sure you're one of the good ones, though.

well I compressed the shit out of everything and then used a CDN and now it's pretty fast

Oh.
