Issue #9243

Updated by dalley over 2 years ago

"touching" existing content and artifacts individually has led to a slowdown on re-syncs of between 30-50% depending on the size of the repo, due to performing (potentially) tens of thousands of extra queries.    Copy is also likely impacted severely however I did not test it. 

 Bulk touch functionality was added to pulpcore by [0], but we must take advantage of it to eliminate the slowdown. 

 See the following spots where touch() is called in a loop: 




 Additionally it would be good to eliminate the extra query here: 

 As this was a significant performance regression introduced by 3.14, we should consider backporting the fixes.    This will include [0] as well which will require a small portion of the refactor introduced here [1]
