Does Indexes Slow Down Inserts. If you have a table with 10 nonclustered indexes, that’s 10x (or more) writes an insert has to do for all of the data pages involved with each index. If you are querying 98% of data in the user table, it is very likely that a full table scan will be faster than using an index because accessing the table takes a longer time. Yes, indexes can impact the performance of data. In this article, we provided some basic guidelines for clustered and nonclustered indexes, as well as which columns are preferred to build indexes on, and which should be avoided. The more nonclustered indexes you have on a table, the slower your inserts and deletes will go. Do indexes slow down insert, update, and delete operations? Indexes and constraints will slow inserts because the cost of checking and maintaining those isn't free. As shown, indexes can speed up some queries and slow down others. A general rule of thumb is that the more indexes you have on a table, the slower insert, update, and delete operations will be.
