    After upgrading to 2.48 I noticed that the CPU usage went much higher than before.
    I downgraded to version 2.46 and the CPU usage was back to normal again.

    I had a similar problem:

    WordPress Version: 3.0.1
    Disqus Comment System Version: Version 2.48

    I disabled the plugin and my site came back.

    Here is a query when the Disqus plug-in was enabled:

    It appears there don't seem to be efficient indices on the table. Definitely a slip up on our part.

    Here's a quick fix:

    create index disqus_dupecheck on wp_commentmeta (meta_key, meta_value(11));

    We will be moving away from the comment meta I guess since it's inefficient for querying against values in WordPress.
