So Many Requests
I make use of wordpress.com for my blogging. I chose it because it was easy, andrelativelycheap. I could have created my ownWordpresssite on Azure or Amazon but it is actually far less economical ($99 a year vs. $570 a years for even the smallest Amazon instance). One really nice feature is that there is an awesome looking page which lists various statistics about your blog. I tell people I don’t care about how many people read the blog but, damn it, if watching that page isn’t addictive.
The page looks like this:
I’ve been on a bit of a vacation for the last week and have had poor internet access and the page seems to take a long time to load. I cued up the network monitor in chrome to see why the page was taking so long to load. The results were shocking to me: the page required 122 server requests. That’s is anawfullot. When I build sites I’m pretty worried at 10 server trips. 10 server trips is a smell. 122 is stinky
This is an easy win: a couple of hours work implementing a concatenation module saves eery one of your users time. Come one, WordPress. Let’s get with the program.
Now for images: combining images is actually pretty easy. You can make use of CSS sprites. Basically all the images on the page are combined into one image and then the client cuts them up into their appropriate sizes. This page is a bit problematic because a lot of the images are gravatars. Gravatar is a service which will transform e-mail addresses into avatars. It is used all over the place now days. The issue is that it only handles one image at a time. So if your page has 40 comments on it, and each comment has a gravatar you’re instantly at 40 server trips. If you’re serious about having gravatars on your site and still having a good user experience what I would suggest is that you build a gravatar proxy. This service would make the gravatar requests on the server side, bundle them as a single image and return it to the client which could split the image. With a bit of a caching policy on the server side you could really reduce the number of trips out to gravatar too.
With these improvements the page would load faster and I would be much happier. We’re talking about no more than a handful of hours work. Come on, wordpress, get with it.
Oh, and in answer to my wife’s question about who the guy in the purple suit is: he is Lawrence Limburger evil mastermind from the cartoon Biker Mice from Mars. There was a running gag that he smelled. You’re always going to learn something at this blog, although it might not be what you expect.
