We see sqlfluff is slow in parsing certain query with nested pattern. Check test case:

test_nested_cast_to_data_type
test_cast_to_data_type_with_case_when
test_column_try_cast_with_func

Let's see if we can submit a PR (or issue at minimum) to sqlfluff community.

sqlfluff v2.1.4 brings some meaningful performance improvements and these test cases are running much faster than previous. See https://github.com/sqlfluff/sqlfluff/releases/tag/2.1.4
