[samigo-team] External Grading provider caching

[David Horwitz]

Hi Sam,

Caching in the samigo provider proved a quick win and easily verify able. The other changes are still undergoing testing and debuging.


I will say that I do believe all this is actulay treatign the symptoms, but the real solution might involve a rewrite of the th gradebook ...

Hi David,


Why not cache the return of the calls inside gradebook instead of modifying all of the various tools that provide external grades?  It seems like that approach was described here:

Hi All,

As part of our investigation of gradebook performance we discovered that the providers where being queried repeatedly in generating a page. As mitigation I've added 2 caches to the externalGradingProvider in SAM:

We're running this in production and it has helped matters. Any objections if I merge to trunk?

Regards

David
