相同的SQL ...但phpmyadmin是快速而PHP是慢的?

I have a simple query that checks for an id and typically returns no results.

On phpmyadmin this query executes roughly at: 0.0004 seconds. On the php server and as mysqli command it takes on average.1 seconds. This is significant for what I'm doing and I would like to close the gap.

It's not a cache issue...as nocaching the query in phpmyadmin still runs fast.

Is this the fault of Mysqli?

Now...phpmyadmin is on the database server, while the webserver is a separate machine. The webserver does connect to an IP and not a domain name though (no need for resolution).

Could persistent connections help?

Ideas for what could be the problem?

Example Query:

select kitchen_id from kitchen_options where kitchen_appliance = 3.

So very small...18 row table. kitchen_id is an int. Typically no results.

Still slow :( But phpMyAdmin is fast...
