      Description

      This is reported by Stanford (CW-88):

      This is a report from a TA, Prang Chaturaphat:

      "I'm a TA for Dr. Dement's Sleep and Dreams class and I'm trying to get to the "Statistics" section of the "Initial Survey" under assignments because Dr. Dement would like to use the results for one of his lectures this week. However, every time I try to get to the page, it ends up just showing the previous page and I have no idea why."

      Site: W09-PSYC-135-01/235-01
      Assignment title: Initial Survey for Sleep and Dreams 2009

      The site membership in this site is very large (almost 500). There are 472 submissions for this assignment. Clicking the Statistics link causes the page to hang (trying to load) until it eventually times out. I am guessing this is a performance problem caused the large number of submissions and the amount of processing required to calculate statistics.

      Expected Result:
      Clicking the Statistics link displays the statistics for the assignment.

      Actual Result:
      Clicking the Statistics link causes page to hang, then time out.
