Is there any way to set the refresh rate?
-
I would like the random posts to not change for a day, if possible, or at least have some control over the time before changing to another post.
This is for a list of members, and we want them all to have some time to be featured.
Is there some way to set that?
Also, I had to Allow ORDER BY RAND() at WP Engine, after having WP Engine support help me to figure out why the posts weren’t changing, and they say this:
“Normally we disable ORDER BY RAND() orderings in MySQL queries because this is a big no-no for large databases which we’ve seen cause massive slow-downs for dozens of our customers. However, you can enable it if you know what you’re doing, for example if you cache the results for 5-15 minutes so that you’re not pummeling the database with these slow queries.”So I was thinking perhaps if there were a time setting, it would also help with the “not pummeling the database” recommendation.
Thank you.
