(fwd)) X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 01 Apr 2009 18:07:34 -0000 All: Has anyone bench-marked the performance improvements associated with various ubsec models in conjunction with OpenSSL cryptodev acceleration of geli(4) in the kernel? I have a sneaking suspicion that I'm a pilgrim on unholy land here. I'm precluding hifn(4), padlock(4), and gblx(4), which are nice for offsetting low power CPUs on embedded platforms, from my question, and assuming that the only supported SSL accelerator that will actually 'compliment', as oppose to 'hinder' a multi-core Xeon system, when offloaded, is ubsec(4)?
