Datatable Per-Column Dropdown filtering lags datatable when filtering over large data

In my list of 6500 names for the datatable, when a user is making their input to the datatable and it starts filtering through the list of names, it makes the datatable lag heavily and the filtering does not visually update fast enough for a pleasant user experience.

Need help with loading the data faster/speeding up the filtering process.

Code based on but with a much larger list to filter.
