Google Page Speed is a tool by Google that calculates your site
certain rules and parameters and come up with the site’s speed analysis.
YSlow grades web page based on one of three predefined rulesets or a user-defined ruleset. It offers suggestions for improving the page's performance, summarizes the page's components, displays statistics about the page, and provides tools for performance analysis.
Both Google Page Speed and YSlow determines site’s speed by some common and some not so common rules. The benefit of GTmetrix is that you can analyze your page using both services, aka. Google Page Speed and YSlow and get different perspectives on how to optimize your code.
With Pingdom’s website monitoring, you’ll be the first to know when your website is down, and you’ll stay on top of your website’s performance. Pingdom's Ping test and Traceroute tools provides network response time helping you to track down possible errors more easily.
for improving the page load times.
According to Yahoo, 80% of a web page’s load time is spent downloading pieces of the entire page – images, videos, stylesheets, etc. That being said, simplifying your design and put less components on every page. Lesser the components, fewer the HTTP requests and faster the site. JS and CSS Optimiser is a great plugin to reduce the number of HTTP requests.
The user's proximity to your web server has an impact on response times. Deploying your content across multiple, geographically dispersed servers will make your pages load faster from the user's perspective. 75% of the retail sites as per one of the surveys do not use CDN.
Make sure that the cache-able resources like JS, CSS files, media files, etc. are set to expire after a minimum of 1 week to a maximum of 1 year according to RFC guidelines. With right enabling of browser caching, atleast the subsequent site visitors will surely encounter faster loading times. Wordpress Plugins like W3 Total Cache is highly recommended although both WP Super Cache and Quick Cache can also improve caching and therefore reduce page loading times.
Inserting a redirect between the user and the HTML document delays everything in the page. Avoid 404 errors especially as every HTTP request will add on to a cost.
Eliminate extra spaces, line breaks, and indentation in your code so your pages are as lean as possible. As per Google, removing unused CSS yields faster page speeds. You can minify the code using CSS minifying tools like YUI Compressor and JS minifying tools like JSMIN. Optimize the CSS sprites. Arrange the images in the sprite horizontally as opposed to vertical for a smaller file size. Also, combine similar colors and don’t leave massive gaps between the images.
22% of the retail sites as per one of the surveys don’t use compression. Reduce the bandwidth of your pages by using compression. It is expected that by 2016, average size of one page will be 2MBs. Reducing bandwidth with tools like Gzip can reduce the page download time by 70%.
The Document Object Model (DOM) is an application programming interface (API) for valid HTML and well-formed XML documents. A high number of DOM elements can be a symptom that there's something that should be improved. 500-700 DOM are alright, but nothing more is good.
HTTP cookies are used for a variety of reasons such as authentication and personalization. Eliminate unnecessary cookies. Keep cookie sizes as low as possible to minimize the impact on the user response time.
Although IFrames allow an HTML document to be inserted in the parent document with a parallel download, they block page onload and are non-semantic. Minimize their usage.
An "entity" is another word a "component": images, scripts, stylesheets, etc. ETags validate the components so that the browser matches it, validates it and sends faster responses from the server. However, if not configured properly the response time increases.
