DataTable sort column slow

Hi,
I filled a simple DataTable with a small dataset of about 200 rows. Everything works perfectly, but sorting is very slow!
Did that

return (
    <DataTable  scrollable  resizableColumns  scrollHeight="600px"  selectionMode="single"
      style={{ minWidth: "50rem", width: "95%" }}
      value={data}
      size="small"
      header={header}
    >
      <Column style={{ width: "15%" }} field="mtr" header="Id."></Column>
      <Column field="val001" header="Name" sortable></Column>
      <Column field="val002" header="Test col2" sortable></Column>
      <Column field="val003" header="Test col3"></Column>
    </DataTable>
  );

Start by reproducing the provided DataTable and Column setup with about 200 rows, comparing sorting on the sortable fields with the other columns. Inspect the DataTable sorting entry point and establish a measurable responsive baseline; done means sorting is acceptably responsive for this dataset without changing the reported table behavior.
