Applying any function or computation on the column(s) in the search predicate generally makes the query non-sargable and leads to higher CPU consumption. Another solution is to create a computed column in T1 that uses the same CONVERT() function and then create an index on it. Figure 5 shows the top 5 of the 10 expensive queries, this time ordered by execution count. Query plans can be obtained from an Extended Events session via the query_post_execution_showplan event.
