A particular work item query takes 15-30 seconds in EWM when a work item type has 100 custom attribute.

A particular work item query takes 15-30 seconds in EWM  when a work item type has 100 custom attribute.

The cause of slowness in work item query is the following

2ms( for attributes check) * 118 (attributes) * 50 row = 11800ms = 11.9 sec.

Please take a look attached log file.


This is a comment by L3 about the cause of slowness.

The intent of the WorkItemFauxSynchronizer is to fake an attribute sync. The case we are trying to cover here then is if:
1) A user adds an attribute to a work item
2) The new attribute is NOT synced to existing work items
3) A query gets run returning work items that could have the new attribute

In that case we are attempting to show the work items as if they were synced, even though they were not. That is why we iterate over all the attributes checking that they are all set, and if they are not then we set as if it was synced. 
The question is: is the performance penalty incurred worth always checking this case? 
We could create an advanced property that disables the check, giving back that time, but with the potential problem of new attributes not getting defined or set if they were newly added and not synced to the existing work items yet.

    Thank you for sharing the details of the customer implementation via email. The performance seems to be because of the high number of custom attributes for one work item. I would recommend that you along with the client to optimize the work item structure and data model for better performance.
