title: Drupal database size
body: <p>I have a site in drupal, at times its really slow have to reboot the server. </p>
  
  <p>I see mysql is consuming too much resources. </p>
  
  <p>I have a core table for drupal devel_times: it contains over 846,000,000 rows and the table itself is about 30 Gb, is that not causing the problem, because I see each time it logs entries, can I empty that table?</p>
