I need some help trying to improve the speed of my script. Heres the two queries..

$sql = "SELECT PadID FROM keywords WHERE Word = '$search'";

$sql = "SELECT Category, LongCategory, PageBase, PageName, ProgramName, 
        ProgramVersion, English250, ReleaseDate, License 
        FROM pads 
        LEFT JOIN categories ON pads.CatID = categories.CatID 
        WHERE PadID IN ($pads) 
        ORDER BY VersionAddDate DESC 
        LIMIT $variable,20";

The first query produced a list of PadId’s which I use a parameter in the second query.

This works find most of the time, however, if I get a call for a very popular keywords the script can take several seconds to run. This morning I had a keyword with 9600 records.

What can I do to fix it.

EDIT: The problem is my site has been scraped this morning, had several thousand calls within a 20 minutes. However the second query takes a few seconds with that many records anyway, so I need to improve it.

    This morning I had a keyword with 9600 records.

    9600 returned records is heavy to load AND neither a helpful search result. (who browses more than five google-search-pages?)

    Narrowing down the RS to 1% would make more sense, consider adding “weight” based on popularity, date etc.

    For best performance, use composite indexes (highest uniqueness).
