View performance remains an issue, eg see https://www.percona.com/blog/2007/08/12/mysql-view-as-performance-troublemaker/.

Some points ...

- try to optimise View algorithm, see https://www.percona.com/blog/2007/08/12/mysql-view-as-performance-troublemaker/ and https://dev.mysql.com/doc/refman/8.0/en/derived-table-optimization.html

- sometimes just one or two subviews are bottlenecks. To find out, you need to assemble the whole query without Views, then substitute in subviews to find bottlenecks

- if all else fails, set up a saved query mechanism, parameterised if so desired, and a user interface for it.
