Use mysql_query instead of $wpdb query

Question

I have a custom table inside my wordpress database called test.

What if i query this table using mysql_query() instead of using for example $wpdb->get_results()

Will this affect my performance?

Ty very much:)

Answer 1

Simple and short:

• mysql_query() = Faster!
• $wpdb->get_results() = Safer!

But in most cases since $wpdb is a global object and already in the memory using it will be be as fast as mysql_query().

Will this affect my performance?

It can affect for better performance changes but they would be minor changes that its just not worth it.

Answer 2

Plugins caching DB queries hook into the WordPress API. If you don’t use the API your queries aren’t cached. The result is a slower site.
