in reply to Optimizing a MySQL Query

  1. use DBI placeholders... (very rough code below) 
    my $sth=$dbh->prepare_cached("select sitename, url, country, language,
+ listing, description from main where category=? and sitename like ?"
+);
$sth->execute($category,$letter);

  2. Make sure your DB has good indexes on category and sitename.

    You add indexes in mysql by writing create index indexname ON main (category) in the mysql program... See CREATE INDEX
