Question

I recently made index on a highly used view but it resulted in increase in Total Execution Time.
Also bytes Sent/received from server incresed drastically.

There are no functions or reference of any other view in it, offcourse schemabinding is on,
just join from two tables.

I am puzzled what to do for increasing performance?

Answer 1

you need to use NOEXPAND query hint to use indexed view.

Use NOEXPAND if you want to be sure to have SQL Server process a query
by reading the view itself instead of reading data from the base
tables. If for some reason SQL Server chooses a query plan that
processes the query against base tables when you’d prefer that it use
the view, consider using NOEXPAND..

 SELECT Column1, Column2, ... FROM Table1, View1 WITH (NOEXPAND) WHERE ...
