An error that prevented content library values from being imported along with ther course data has been resolved. When you import a course that includes randomized content blocks, the Display Name and Max Attempts values are now correctly imported along with other problem settings. (PLAT-1046)

Before this change:
After this change:
Over the last two months, a series of incremental improvements have been made to grade computations. As a result, system performance for loading the learner Progress page has increased significantly over the past three weeks.
The graph that follows shows the effect of the first of these changes, which released at approximately 1:00 pm EDT on 29 Jun 2016. The graph shows a significant drop in response time, from eight seconds to approximately four seconds, immediately after the initial phase of the work was released.
Subsequent performance improvements were then made that built upon this initial transformative change.
The graph that follows shows a comparison of how long it took to load the page, in seconds, for the two week period from 29 Jul 2016 to 11 Aug 2016 to the period two weeks immediately prior. The graph on the top compares median durations, and the graph on the bottom compares 95th percentile durations for these time periods.
