Description

While working on enhancing the performance of range queries, I noticed majority CPU cycles being spent on readInts24() & readDelta16().

I noticed a PR trying to optimize readInts24() by reducing the number of sys calls, but the results did not resulted in considerable improvements.

Trying to gather inputs from community on other areas of improvements to be explored in the 2 methods listed above.
