How to read this tiny time number, and whats the improvement between these 2 times -

i developed in c sharp, 1 alternative without caching , 2nd alternative caching.

without caching time returned app is: : 00:00:00.3873553 how read that? 387 milliseconds?

with caching: 00:00:00.0000176

is nanoseconds, microseconds? how can read this?

now, if want compare both, whats % improvement?

the fractionall part represents milliseconds. 4 heading zeros in 0000176 indicating value of 0.0176 ms.

387 ms 21988 times 0.0176 ms. caching need 0.0045% of time.
