Subject: Re: [dpdk-dev] [PATCH v2 1/7] test/hash: fix bucket size in hash perf test
Date: Thu, 27 Sep 2018 03:39:54 +0000	[thread overview]
Message-ID: <D2C4A16CA39F7F4E8E384D204491D7A6614BEFEB@FMSMSX151.amr.corp.intel.com> (raw)
In-Reply-To: <20180926100441.GA20648@bricha3-MOBL.ger.corp.intel.com>

Hi Bruce,

In the test, the bucket size and number of buckets are used
to map to the underneath rte_hash structure. They are used
to test performance of two scenarios: keys in primary
buckets only and keys in both primary and secondary buckets.

Although there is no functional issue with bucket size set
to 4, it mismatches the underneath rte_hash structure (i.e. 8),
which may affect code readability and future extension.

I added this description into the commit message.

Thanks
Yipeng
