depends on concurrent connections vs spread out, cpu, traffic of other customers on your box, apache configurations, etc... It's just good practice to cache when you can. There is no reason to ask the database for the same article 1000 times a second if it's not changing. I didn't feel the server was going to crash at that moment but I did notice MySQL was doing plenty of work it didn't need to. The concern was if it got picked up by another site like digg or reddit then it could have been more of an issue.
