Does the performance of the kvstore lookup definition improve when it filters the original collection?

When a kvstore lookup definition filters a kvstore of 1 million events down to 300k, does performance improve vs using the original kvstore collection unfiltered?

filter = <string>
* Filter results from the lookup table before returning data. Create this filter like you would a typical search query using Boolean expressions and/or comparison operators.
* For KV Store lookups, filtering is done when data is initially retrieved to improve performance.
* For CSV lookups, filtering is done in memory.

It looks like performance is improved after the filter is applied on reading the kvstore.
