Waiting For Webiste slow registering action php?

If you're concerned about slow PHP scripts, there are a few ways of troubleshooting. Since I can't see your internal configurations, I ran a couple commands from my end to see what I could find out.

First I sent a cURL:

time curl -sIL patpro.ca/wp/users-posts/
HTTP/1.1 301 Moved Permanently
Date: Thu, 23 Jan 2020 00:30:24 GMT

HTTP/1.1 200 OK

There could be a few reasons for this, and I did some digging online and found what looks to be a pretty good resource on Stack Exchange, which I will link here:

PHP request sometimes very slow

One of the suggested solutions is to check out your Apache, and maybe do some tuning. This is my first go-to in situations like this, too. We have a great guide for tuning your Apache web server here:

Tuning Your Apache Server

I sent a ping to your website, and while it responded to that ping there was a bit of packet loss:

--- patpro.ca ping statistics ---
7 packets transmitted, 6 packets received, 14.3% packet loss
round-trip min/avg/max/stddev = 39.349/41.117/44.045/1.809 ms

If you think this might be a network issue, you can use MTRs to troubleshoot. I'll link you to our guide on those here:

These are just some suggestions to get you started. I hope it's helpful to you.
