We will discuss today on the Linux cron job versus WordPress con job and which one is better and how to schedule wordpress cron to optimise the use of expensive resources like CPU and RAM.

Understanding the Linux/Wordpress Scheduler Job      ( Do not Miss this Part )

Do the change

Set up the linux cron job for wordpress every five minute.
