BizTalk 2013R2 SQL Query Timeouts - sql

Question

Using BizTalk to call a SQL Server stored procedure (see below), which:
Writes data to 5 tables
Checks each table to see if the record exists
Updates or Inserts accordingly
The problem is that when BizTalk receives hundreds of calls, the stored procedure is called each time which appears to add an overhead to the SQL Server and eventually causes timeout errors returned in BizTalk, resulting in the data not being written to the database.
Can anyone advise on the best way to optimise my query so that it processes these tables without much overhead, or have I got it optimised enough already?
