If you read this, then it is because you are interested in the impact of missing indexes. What does it mean, that the SQL server and SQL Powerhouse suggest some indexes for you?
This short video will show you a very simple example of why indexes are important.
NOTE!!! We are only looking at read performance. any changes to any data structure or any new indexes must be planned and examined. A new index cause degraded write performance and takes up space, but it can improve read performance.
