-----------------------------------

             Summary: [Python] Slow performance in test_parquet.py::test_set_data_page_size
                 Key: ARROW-7614
                 URL: https://issues.apache.org/jira/browse/ARROW-7614
             Project: Apache Arrow
          Issue Type: Bug
          Components: Python
            Reporter: Wes McKinney
             Fix For: 1.0.0


Slowest test durations:

{code}
3.73s call     pyarrow/tests/test_parquet.py::test_set_data_page_size
0.05s call     pyarrow/tests/test_parquet.py::test_nested_list_nonnullable_roundtrip_bug
0.03s call     pyarrow/tests/test_parquet.py::test_compression_level
0.03s call     pyarrow/tests/test_parquet.py::test_dictionary_array_automatically_read
0.02s call     pyarrow/tests/test_parquet.py::test_statistics_convert_logical_types
0.02s call     pyarrow/tests/test_parquet.py::test_large_list_records
0.01s call     pyarrow/tests/test_parquet.py::test_write_nested_zero_length_array_chunk_failure
0.01s call     pyarrow/tests/test_parquet.py::test_parquet_write_disable_statistics
0.01s call     pyarrow/tests/test_parquet.py::test_single_pylist_column_roundtrip[int]
0.01s call     pyarrow/tests/test_parquet.py::test_special_chars_filename
{code}

This suggests to me there is something wrong with the feature (possibly doing unnecessary work)
