Analytics Center takes too long to generate visualization given high amount of data on instanceDescriptionWhen using the Analytics Center's Q&A functionality, it can be the case that requests are taking rather long. This can be due to instance performance bottlenecks or having many records in the related Performance Analytics tables. The workaround makes use of enabling a cache, that changes it such that the result of parsing these tables' schemas, is cached for future use. This can decrease the time it takes for Analytics Center's Q&A to give a result significantly, however, there is a drawback to using this property. Until the defect is fixed, requests made on the very first time will still take long, as the cache needs to be populated with the necessary information. Steps to Reproduce 1. Log into a ServiceNow instance with a lot of Performance Analytics meta data, in particular, many breakdown relation mappings (between breakdown elements and records)2. Go to the Analytics Center3. Type in an utterance question such as "Number of open incidents in the last 60 days"4. Wait for result Expected: The answer comes back in a reasonable amount of timeActual: The answer comes back within often, 2 min or longer. Even a minute seems to be excessive.WorkaroundNavigate to system propertiesEdit/Insert the property com.snc.par.nlq.pa.metadata.use_cache and set its value to true Related Problem: PRB1795659
