We are in the process of upgrading a customer from version 10.4 to 10.19.14, which all seems to be working fine, except for when trying to synchronize content out of Dynamicweb.
Previously a full sync of an area took 2-4 minutes in version 10.4, but now it takes up to 45 minutes if the task does not time out all togehter.
I’ve done some digging and locally added APM to track what the differences between the same call to identical databases between version 10.4 and 10.19 which shows that before I could hit a cache and have NO SQL calls at all, while now I always get around 500 SQL calls.
I took it a step further and think I have isolated the issue to the MetadataManager class which now syncs items for every access regardless of the number of item sources, where it before only did so if there were more than 1 item source.
