Database result serialization.
Yes it does. Hey, didn't you ask this question over on my other plugin too?
$cacheMoney->threshold to whatever number of seconds you wish.
The directory wp-content/plugins/wpdb-cache-money/ should be full of files with names similar to
4a13fc6a615ac14cc3f58160ce9c52f3.php. If not, check to make sure this directory is writable by your server.
echo $wpdb->stats(TRUE) will give you a result like
q: 9 | c: 6 | m: 9.055 t: 0.171.
q is the number of actual database queries,
c is the number of cached queries,
m is the memory usage in megabytes, and
t is the time in seconds to render the page.
echo $wpdb->stats() will do the same, wrapped in an html comment, for times when you need to be discrete.
There is also a profiler method -
echo $wpdb->profiler(). You will need to make sure
$cacheMoney->useProfiler is set to
TRUE to use this. The default for the profiler is to sort the queries by length of time descending.
$wpdb->profiler(FALSE) will show the queries in the order performed.
