Frontend render speed too slow

When I query a question from a clickhouse data source . Total cost 21 seconds , network api response cost 5s , local browser render cost 17s .
How to speedup render ? Or why this part costs so much time?

We’re working on that. It will be available in 47.2

When will 47.2 be released ?

This week

It works! We have updated to 47.2
