[UI] Cluster Documents: Bad response time - Taking more time (>1 to 2 mins) to fill bucket details and retrieve the documents when 1000 collections created

It has been observed that when 1000 collections (500 scopes x 2 collections in each scope) and 100 documents loaded in each collection, then when clicked on the Documents on a particular collection, then it is taking more than 1 or 2 mins to load the Location: bucket.scope.collection and also showing the documents in the collection.
It seems a bad response time and appears that no documents at all or no buckets at all. After that long, it does shows the data correctly.
It is better to improve the response time to load in such high number of collections. It was never observed before with few collections or default bucket alone.
Not sure if it is a backend issue but UI is exposed.

Tested using Chrome browser on MacOS with Couchbase 7.0.0-3570 build on Linux host.
