PostHeaderIcon Web Site Latency and Site Performance Part 5

Well, it’s Monday. A good Monday with some interesting insights.

I will continue with tool review going forward, but I’m finding that I need to document our work on our website performance as we go along or else we lose the data from the intermediate steps, and there have already been several that have been implemented. So let me bring you up to speed.

After my last post about the site and reviewing the data from the Google Site Performance tab in Google Webmaster tools, I was able to visualize (see the image) what was going on. As the image shows, performance jumped around substantially from mid-September, when I started the blog, until early-mid December. These jumped did not coincide in any major way with the debugging and latency improvements that I had been working on. Except for December – around the time of my last post. That seemed to have cut my latency in half – which was what pingdom had shown. So perhaps I was moving in the right direction.

Things continued to improve steadily through January – even though I had not changed any further settings. This again suggested that the fact I was hosted on a shared server and that perhaps my ISP had improved the performance of that server might be the reason for unpredictable performance changes, good or bad. But then in mid-January, I started to see a jump in latency times again.

At the same time, I wanted to continue debugging AboutOnlineMatters site latency and implement some of the changes from ySlow, such as gzip, entity tags, and expires headers. To do that, I needed direct access to my Apache Server. Given these two facts, I decided that it was time to remove the server as a factor and host the blog myself.

On February 6, we moved the site onto our own hosted setup. This is basically a dedicated server (we do have a few other small sites running, but they are using insignificant server resources) and I have direct access to all the configuration settings. From that time forward, as the chart shows, site latency has decreased continually until it is now at close to it’s historical lows.

I’ll leave it there for now – following my rule of short posts. We’ll pick up the next steps I took tomorrow.
