I’ve setup APO on a couple of sites (Pro account) and everything appears to be working correctly.
I get the appropriate cache hit response.
Yet performance is all over the place. I’ve run the below test many times and I’m getting completely random TTFB results, from a <100ms to 6 seconds, from the same locations. The same tested locally as well, pages just seem to occasionally hang. All served as a cache hit.
The next time I ran, Montreal is showing 4.2 seconds and Toronto is showing 70ms. run again and now Australia is 45ms but Iowa and Vegas are 2 seconds+
I’ve also noticed that pages are randomly expiring after an hour or so. I don’t believe there is anything in the headers which would cause this. Browser TTL is 4 hours. Do inactive pages really get cleared out after just an hour of not being in use?
