I just started to notice this phenomenon in the last 24 hours.
This is the test results, and if you notice on process #1, it takes an incredible 16 seconds for the content download of www.headfonia.com, before everything else starts to be downloaded. The same behavior occurs even on repeat views. Previously first view takes anywhere from 6-8 seconds, and repeat views are a consistent ~0.6 seconds on Chrome from the Dulles, VA test point.
But now even repeat views take as long as 13 seconds due to the unbelievably long first process, and I don’t quite now what’s causing it.
Here is the test results:
None of the caching set up was changed, nor any major changes were performed before this slow down happens. So as far as I’m concerned, the site is still the same site. The site is running on the latest Wordpress, W3TC, Amazon CDN, and APC cache for page, object, and database cache.
Any help is appreciated. Thanks!
