add pluggable nanosecond timer #7

Allow use of a native RDTSC call in place of System.nanoTime().

ifesdjeen commented 7 years ago

I think using a hashed wheel timer defines a native RDTSC timer. The latter suggests precision, while former deliberately trades precision for performance. So far nanoTime wasn't known to cause any performance trouble (unlike getCurrentMillis), but I'm willing to revise that thought if anyone has a good benchmark.

I wrote an article on this: based on these findings I think you are right to close the issue.
