OPTIM: vars: do not keep variables usage stats if no limit is set The sole purpose of the variable's usage accounting is to enforce limits at the session or process level, but very commonly these are not set, yet the bookkeeping (especially at the process level) is extremely expensive. Let's simply disable it when the limits are not set. This further increases the performance of 12 variables on 16-thread from 1.06M to 1.24M req/s.
