This plugin will track all incoming requests to your server that triggers loading WordPress core:
- regular pages
- 404 page
- login, register and lost-password pages
- ajax, rest & xmlrpc requests
- cron requests
Somewhat similar to "access log" feature most servers already has,
but with one important improvement - it stores how long each process executes!
That information is essential for analyzing stress test results.
Now we can visualize what requests was ran in parallel with other requests, competing for resources of the same CPU.
Now you can see are your pages loading so slow because there is cronjob working in background.
