ESF filtering is substantially slower than advanced filtering

[ChronosSF]

Description

Performing similar filtering operations through AFD and ESF seem to take widely different amount of time without clear reason why.

• igniteui-angular version: latest
• browser: n/a

Steps to reproduce

1. Open the attached sample
2. Filter HireDate through ESF to display only one of the distinct values. It takes forever.
3. Filter HireDate through AFD to do the same. It is almost instant.

Expected result

Filtering through ESF cannot be that slower than AFD filtering. There is a bottleneck somewhere that needs to be fixed.
