Optimistic should show better performance than pessimistic transactions.

The main point about OPTIMISTIC READ_COMMITTED is that during a commit it’s not checked
if an entry value has been modified since the first read or write access and an optimistic
exception is never raised. However OPTIMISTIC SERIALIZABLE will detect such a situation and
throw the optimistic exception allowing you to perform a transaction one more time.

You can read more on optimistic modes here:
