Had to troubleshoot my website as it kept getting slower and would spit 500 errors.
Turned-off all the plugins and re-enabled them one by one while testing to see which ones had the biggest hit on performance. Stock Quote Sidebar was dragging the WP system. Even though my other websites on the same server ran fine the site with SQS on it was slow.
Deactivated it and now the site is zippy again. Might have to look for another solution or just forget about using stock quotes as a sidebar widget.
