Subject: [dpdk-dev] [RFC PATCH 1/2] lib/librte_eal: Reduce timer initialization time
Date: Tue, 17 Nov 2015 22:27:10 -0500 [thread overview]
Message-ID: <1447817231-10510-2-git-send-email-zhihong.wang@intel.com> (raw)
In-Reply-To: <1447817231-10510-1-git-send-email-zhihong.wang@intel.com>
Changing from 1/2 second to 1/10 doesn't compromise the precision, and a 4/10 second is worth saving.
