A published study showing extensive data on the DEC VAX summarized statistics for the $10$ most frequent instructions and the $10$ instructions responsible for the most execution time for a particular workload.

What speed up of the workload could be achieved if the BBS $($branch on bit set$)$ instruction could be speed up by $50\%?$
