The service will return to operation well before 8:00AMLearn@Illinois Upgrade on Wednesday, November 11thNov 9, 2015 3:00 pm4 views On Wednesday, November 11th, starting at 4:00AM (one hour before our normal maintenance window), we will be updating our Learn@Illinois system. The main purpose of this upgrade is to alleviate some of the gradebook slowness that many users have been experiencing this semester, especially in large courses. We anticipate that we will be done well before 8:00AM which is the normal end of our maintenance window. While our tests have shown significant improvement in gradebook performance when conducting normal tasks such as moving grades from one column to another, we are going to continue to work to improve performance even more. Making the gradebook even better is still the primary focus of our January 2016 upgrade. The major components of this upgrade include: Upgrading the Moodle version from 2.8.6 to 2.8.9 which will capture improvements made by the core Moodle developers. Changing the default so that each grade's contribution to the total score for each student is hidden. This has been a major cause of the slowness that large courses have experienced since this value had to be recalculated any time any grade operation was completed. Not calculating this value when the item was hidden in the Gradebook User Report. If you have any questions about this upgrade, please drop us an email at firstname.lastname@example.org. Thanks,The Learn@Illinois Development TeamGradebook Slowness UpdateNov 5, 2015 1:00 pm6 views Hello Users, We have been working on a solution to the gradebook slowness that has been a big issue this semester, especially for larger courses. We installed an upgraded version on our shadow system that you are welcome to try out. The shadow system is navigated much like production and can be accessed at https://shadow.learn.illinois.edu. This system is a duplicate of our production system and is only to be used for testing purposes. Any work that is done on this system can disappear at any time and the database is usually overwritten every night. So please use the shadow system only for experimentation and not to do any work you wish to keep. We would advise against sending students to this system except in very limited cases. Please keep in mind that the shadow system is running less robust hardware than production so performance here will be slower than when it is implemented on production. Also note that the theme on our shadow system looks different than on our production system and that we had a little fun with cat pictures. Much of the current slowness seems to stem from Moodle calculating each grade’s contribution to the course total which is a column that is shown on the gradebook user report. This column can be hidden under Course Grade Settings (which can be accessed from the drop-down menu after accessing the course's gradebook), though the current system would still calculate it regardless of this setting. The new version brings three main changes: If the "Show contribution to course total" is set to hide, this value will not be calculated. We have made this setting hidden by default for all courses. Upgrades in the latest version bring additional performance improvements on the backend as well as fixing two grading bugs The result of these changes is that gradebook performance is greatly improved. In one test, operation that took ~350 seconds with the old method took ~21 seconds with the new code. The course we tested this in has over 1700 student enrollments. We are still in the process of doing final testing on this fix, and we are going to continue to work on making the gradebook performance even better. These fixes will be implemented on our production server on Wednesday morning the 11th assuming the rest of our testing goes well.
