Question

I’m writing a benchmark for computing the time taken for serialization/de-serialization for OpenFast

The question is when I’m computing the time taken, should I also take into account the time taken for parsing and setting the values for fields and also the same while de-serialization.

I’m writing it in java so what accuray is good Nano or Milli? Are there any issues in nano second computation that I should be worried about?

Thanks.

Answer 1

From Effective Java, Edition 2, Item 69:

For interval
timing, always use System.nanoTime in preference to System.currentTime-
Millis. System.nanoTime is both more accurate and more precise, and it is not
affected by adjustments to the system’s real-time clock.
