Well the other day I improved the performance of a particualr piece of code from 34sec to 2 sec and I was calcuating the percentage for the same i.e (34-2)/34 i.e 94.11 percentage and when I told this number out in a meeting people were not that amazed.. I am wondering if that was a wrong number that I communicated..
How do you generally measure the improvement and look good at the same time?

Some math behind running improved time = 95% of race time and a formula for that: improved time = race time * 0.95 - here it is!
To calculate the percentage of monthly growth, subtract the previous month's measurement from the current month's measurement. Then, divide the result by the previous month's measurement and multiply by 100 to convert the answer into a percentage.
((old time - new time) / old time) * 100 This formula will give the Percentage Decreased in New Response time.
Speed (or throughput) is proportional to the reciprocal of time. So it's actually a factor of 34/2 = 17x faster (which you can state as a (34-2)/2 = 1600% speed increase if you want to sound impressive).
