Speedup / Faster terminology when benchmarking -



Speedup / Faster terminology when benchmarking -

although not programming question, came when writing paper.

while comparing performance of 2 threading implementations, implementation a had execution time of 1500ms , implementation b took 2000ms.

the ratio of timeb timea 2000/1500 = 1.33.

it right state b requires 133% time of a.

it may right a has 133% performance of b.

but: more right state a 133% faster b, or a 33% faster b ?

is there reason why of 2 latter statements blatantly incorrect? matter of convention?
