"Which domain? All of them?"
Yep, all of them. As far as I can tell. But the one I REALLY care the most about is my business site.
Maybe I'm doing something wrong...
I notice a long delay in page loading. Let's say, this page, which is both typical and popular:
So, first, I run the page through here:
Result load times (five tests): 18.85s, 20.36s, 25.86s, 13.35s, & 28.92s
Seems like the HUGE majority is the very first load result.
The second-most troubling bit is the custom CSS (which I understand WordPress recompiles for each page load, which I think is stupid, but I'll roast that donkey later), but that looks like only about 1/6 of the load time as that first acknowledgement.
The seven slider images are 83.1kB, 54.7kB, 96.6kB, 57.4kB, 62.6kB, 56.3kB, & 61.6kb. Of the seven images, the longest load time was 43 uS. So -- while I may be outta my league a bit -- I don't think they are the problem.
So, that was one test site.
At another test site:
I ran the same page (Features_FOMF.html)
Result load times:
Test 1 First View: 28.634s
Test 1 Second View: 23.069s
Test 2 First View: 21.889s
Test 2 Second View: 28.571s
Test 3 First View: 21.330s
Test 3 Second View: 11.337s (well, isn't THAT weird!)
Test 4 First View: 41.231s (ha-ha, fooled me twice!)
Test 4 Second View: 29.290s
When I examine the waterfall of these results, again, the very first line is doing all the I-Hate-Your-Users heavy lifting.
It SEEMS like the browser makes the request and then the server runs off to the bathroom for a minute before bothering to respond. Could that REALLY be just WordPress spinning up? Could it be some Random Joe who is also hosted on my server doing some random thing?
