Preload with Cron

Sorry one other thing – is the speed of this process determined by the speed setting of “X pages per minute” in your settings?
Cheers.

yes, you can increase the number but I do not recommend it. it may cause lots of cpu usage.

if I run:
https://virtualdesigncloud.com/?action=wpfastestcache&type=preload

Why do I get 4 pages being cached (there are lots more on this site) and ‘page: 0/39’?

Here’s the output:

OK https://virtualdesigncloud.com/new-design-agency-in-cambridge/ (desktop)
OK https://virtualdesigncloud.com/virtualdesigncloud-wins-best-creative-design-agency-award/ (desktop)
OK https://virtualdesigncloud.com/cambridgeshire-tech-startup-shortlisted-for-top-rural-award/ (desktop)
OK https://virtualdesigncloud.com/witchford-design-agency-awarded-7500-from-european-union-via-cambridgeshire-fens-leader-program/ (desktop)

4 page have been cached

homepage: 1/1
post: 12/30
page: 0/39

because you have set tne preload number as 4 via the preload settings. Actually it is ok. I do not recommend you to increase the number.

I recommend you to set a cron job as below to speed up the preload.
