From 4c75804c85ffa7ef236fff24ea8d159ca2dc73b7 Mon Sep 17 00:00:00 2001 From: Peter Mikus Date: Wed, 28 Feb 2018 10:13:12 +0100 Subject: Performance KW optimizations II Currently Binary Search is using TRex warmup time for every lookup trial. This patch is suppose to optimize Binary Search to not use warmup time for each trial apart from first one.
