reading xml faster than DB call?

Posted on 16th Feb 2014 07:03 pm by admin

I am trying to optimize a high traffic website, and I enabled a feature where there are three photos selected from the most recently submitted ones, and displayed at the top of the page. I figured that if each person is asking for 3 photos every time the page loads, this will put strain on server load. My solution involves having a script generate an xml file of the 30 most recent photos every half hour, and then cycle through the xml on the actual page. Is this a better solution than making a db call, in terms of speed gained/efficiency? I dont have much experience with XML so I wouldn't know how fast parsing it in PHP would be compared to a database call.
