> The only performance optimization we've made so far is to ensure that the
> call to pre-load stored procedure parameters borrows the already-open
> connection of the IDalSession above it. We saw that under super-heavy load
> the fact that the sproc parameter populator tried to grab its own connection
> within the connection of its parent that a semi-deadlock situation would
> result, because the parameter populator does all its work in a heavy lock.
> Interested in hearing why this was done, because we definitely got a big
> boost on app startup post-optimization.
