In January, I interviewed Kyle Simpson on Episode 4 the ATX Web Show. We discussed Web Performance and Google’s plan to “Make the Web Faster”. Since then, Google has announced they will start rewarding your site’s page speed. And in their Webmaster Tools they hint that the bar is set at ~1.4 seconds.

80% of the time users wait for a web page is because of the frontend.

Web Performant

I was sort of thunderstruck with fear. Although we always strive for better, I typically found a 3-5 second page load great and up to 7 seconds acceptable. After recording the show, I stayed up a few hours that night fiddling with The ATX Web Show and increased site performance by ~500%1.

Since seeing those results, I only think about Web Optimization. I see the web in milliseconds now. If you’re like me and never considered optimization a necessity maybe now is the time to re-evaluate that. And don’t act like this isn’t your problem because 80% of the time users wait for a webpage is because of the frontend2. The goal isn’t to fit under some imaginary kilobyte threshold, the goal is to make sure that everything is as small as possible. Reduce Filesizes, Reduce Requests, and Enable Caching.

We have transferred numerous client websites, and sometimes a WordPress Memory Exhausted error shows up when activating a new plugin or doing some other task. Usually the error looks like this:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 2348617 bytes) in /home4/xxx/public_html/wp-includes/plugin.php on line xxx

We got an email from a user who was facing the same problem, so we decided to do a writeup on it because this is a common problem. The reason why this error shows up is because you exceed your default Memory Limit. There are numerous solutions for it, but in this article we will share the simplest one out of all.

First open your wp-config.php which is located in the root WordPress directory. Then add the following line inside the main php tag:

jsPlumb is jQuery plugin that allows us to connect elements on the screen with “plumbing”, using a Canvas element when supported, and Google’s ExplorerCanvasscript to support older browsers. It’s written as a jQuery plugin, and relies on jQuery 1.3.x or jQuery 1.4.x (tested on 1.3.2 and 1.4.2), and also jQuery UI 1.7.2 (if you want to support dragging). For Canvas support in IE you also need to include Google’s ExplorerCanvas script.
