Minimal test file

Filtering in column A takes 14s in my PC. 

This may due to column A contains too many unique values. I do encounter many
cases when autofilter takes a lot of time when the field contains a lot of
unique values in my daily work.

Attached is a minimal test case. Column A contains too many unique values:
filtering in this column takes a lot of time. Column B contains only 3 unique
values: filtering in this column takes only < 1s.
