Back when I was just getting started, we were doing a lot of WordPress stuff. A client contacted us, "oh yeah, later today we're probably going to have 1000x the traffic because of a popular promotion". I had no idea what to do so I thought, I'll just set the varnish cache to 1 second, that way WordPress will only get a maximum of 60 requests per second. It worked pretty much flawlessly, and taught me a lot about the importance of request coalescing and how caches work. |
