From 740b97f9509ac5a015278940747178af4eb0900d Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Mon, 22 Dec 2014 13:44:10 +0900 Subject: perf report: Show progress bar for output resorting Sometimes it takes a long time to resort hist entries for output in case of a large data file. Show a progress bar window and inform user.
