Subject: Re: [dpdk-dev] [PATCH v2 0/4] rte_hash_crc reworked to be platform-independent
Date: Tue, 25 Nov 2014 09:05:13 -0800 [thread overview]
Message-ID: <20141125090513.3edd3b50@urahara> (raw)
In-Reply-To: <5469E1ED.4040109@sts.kz>
I found that other hash functions are faster than the crc32 SSE instruction.
Though the hardware instruction seems like it would be faster, it takes more
cycles than simple multiplicative or murmur hash.
