I don't think performance is even the main issue. We have never
recommended having Asserts on in production because they can decrease
system-wide reliability. As per the fine manual:
The assertion checks are not categorized for severity,
and so what might be a relatively harmless bug will still lead
to server restarts if it triggers an assertion failure.
