The SitePoint PHP blog has a new post sharing some general web performance tricks that could be done to any application to speed things up a bit. Note that this is a sponsored article but it does not promote the sponsor's product.
We've had a lot of performance talk over the years here at SitePoint, and we believe it's time to revisit the topic with some more advanced aspects. The approaches mentioned in this article won't be strictly PHP related, but you can be sure they'll bring your application to a whole new level if used properly. Note that we won't be covering the usual stuff - fewer requests for CSS, JS and images meaning faster websites and similar hints are common knowledge. Instead, we'll be focusing on some less known/used upgrades.
Their list of suggestions include things like:
- Removing unnecessary HTML tags
- Prefetching and caching content
- Using tools like CSS Lint and CSS Explain
- Using Google's Page Speed tool to find bottlenecks
- Use things like SPDY, WebP and Zopfil
