    Im not sure if it made a difference cause its hard to tell on a shared server.

    In the db-functions.php file i changed the load function to:

    function load( $tag = ” ) {
    if ( $tag == ” ) {
    return false;
    }

    $file = $this->storage.”/”.$tag;

    $result = unserialize( file_get_contents( $file ) );

    return $result;
    }
    `
    on line 775 in db-module.php

    old: $dbcr_queryid = md5($query);
    new: $dbcr_queryid = hash(‘md5’, $query);

    i read somewhere that hash is much faster

    also when cache new results it was serializing the query results twice so i removed the second one in db-functions.php and deleted line 884 ish.

    $dbcr_cached = unserialize( $dbcr_cached );

    Everything’s working fine, and technically it should make a speed difference.

    Thanks for your post.

    The part of function load() which you removed is responsible for removing cache files which are too old. So this code have to be here. I can think of alternate solution for this – e.g. use of WP Cron.

    Hash() function is a bit faster than md5() – benchmark results are on page with description of hash() function. Unfortunately it is supported starting from PHP 5.1.2. I could drop support for PHP 4 (it was supported until end of 2007 only). I could add check if this function exists, but additional call to function_exists() overcomes speed benefit of hash(), so everything is slower than md5(). Therefore I will keep md5().

    I have to check the last change, and will include it in official release if needed.
