Description:
Due to the CVE-2022-21724 we upgraded our driver from 42.2.22 to 43.3.3.
We've now started to see a large perf degradation during initial opens to the
database.
With a small perf test that just opens and tries a "select 1" we're getting
a ~2 - 2.5x slowdown on the connect times. Is this a known issue or
something that we can work around?
