From 3314b3a2f5d9abcf1deee565839f779d26c8672d Mon Sep 17 00:00:00 2001 From: Kenny Yuan Date: Wed, 27 Jun 2018 12:42:18 +0800 Subject: benchmark: add n-api function args benchmark This benchmark suite is added to measure the performance of n-api function call with various type/number of arguments. The cases in this suite are carefully selected to efficiently show the performance trend.
