From 3a4c1dc58bc7beb67e9ca8c186b6278fb0bc5f04 Mon Sep 17 00:00:00 2001 From: David Hunt Date: Thu, 26 May 2016 15:15:54 +0100 Subject: [PATCH] app/test: fix wraparound of mempool performance rate Recent CPU's can easily wrap around a 32-bit unsigned int in the mempool perf test. Increase to a 64-bit uint.
