hi you can lower the load by using memcached or redis
for wordpress tutorial :

You need checking SQL queries (mysqladmin pr) and ask the website developer to optimize it

i am using wordpress , and publishing posts nearly one post every five minutes.

how can i check SQL queries (mysqladmin pr) please?!

 Why are you still running php 5.6 and not upgrading to php 7.3?

That memcached plugin I note had php7 in its url.

@leebrimlow
the command: mysqladmin pr will show to you the queries at the moment.
