I posted earlier about my attempts to improve my site rendering speed by upgrading my blog server’s RAM. As I noted in that post, it didn’t seem like the changes made much if any difference to the rendering speed in the Safari browser.

After much experimentation, I can hereby clarify/correct all of my previous observations and guesses. The rendering speed problem is not related to my server’s RAM nor is it the fault of the Safari web browser. Instead, my site renders slowly for me because I am logged in as the WordPress administrator for the site.

Boy, do I feel dumb now. Allow me to explain in order to hopefully prevent you from feeling dumb as well.

Blog web server upgrade

I have completed a simple upgrade to the little box that serves my blogs. I have increased its RAM from 16 gigabytes to 64 gigabytes.

I had observed some page loading slow-downs under some conditions recently. My quick review gave me the idea that some of the blogs processes might be a bit starved for memory. Too much of the system’s work seemed to be regularly swapped to virtual memory swap (SSD), a condition generally to be avoided.

The change in memory capacity and process configuration seems to have made the blogs a bit more responsive. However, it appears that most of the slow rendering I’ve noted relates more to Safari behaviour with the content of the site than with any shortcomings of my server hardware.

I’ve included some more detail below the ‘Read More’ fold for those who are interested.

Optimizing WordPress performance

My blog doesn’t get a lot of traffic. It has never been referenced on Slashdot. No one Diggs me. Basically, folks who find my site do so via a search engine, more or less by accident, or are friends and family. The fact that my site has been here at kgadams.net for a number of years and I’ve made an effort to make sure I keep the search engines moderately happy means that I get *some* traffic: maybe ten thousand hits a month, more or less. Just so we are on the same page: many “moderately popular” websites get that many hits in an hour. Seriously popular sites get that many in a minute.

But despite the fact that my site isn’t generating massive influxes of visitors, I still care about performance. It bugs me when my main page takes more than a second or two to generate, or when my administration interface takes ten seconds to appear. So what do I do to improve responsiveness? Well, I visit another blog…
