What sort of hifn card were you using in the test below, was it a 7956 PCIX (ie., 64bit?) How did you measure the throughput ? I can post the OCF numbers, but it doesn't mean a lot unless it's a fair comparison :-) Cheers, Davidm Jivin Evgeniy Polyakov lays it down ... > New asynchronous crypto layer acrypto [1] release. > It includes new driver for HIFN 7955/7956 adapters, > VIA padlock driver, driver for CE-InfoSys FastCrypt PCI card equipped > with a SuperCrypt CE99C003B and > dm-crypt and IPsec ESP4 engines ported to acrypto. > > Psec ESP4 transport mode benchmark (scp): > 2.6.16-1.2069_FC4smp -> vanilla 2.6.16-git: ~11.8 MB/s > vanilla 2.6.16-git -> 2.6.16-1.2069_FC4smp: ~13.2 MB/s > > 2.6.16-1.2069_FC4smp -> acrypto SW 2.6.16: ~12.6 MB/s > acrypto SW 2.6.16 -> 2.6.16-1.2069_FC4smp: ~13.5 MB/s > > IPsec benchmark with HIFN driver: > 2.6.16-1.2069_FC4smp -> vanilla 2.6.16-git: ~11.8 MB/s > vanilla 2.6.16-git -> 2.6.16-1.2069_FC4smp: ~13.2 MB/s > > 2.6.16-1.2069_FC4smp -> acrypto HIFN 2.6.16: ~13.2 MB/s > acrypto HIFN 2.6.16 -> 2.6.16-1.2069_FC4smp: ~13.5 MB/s > > As you might expect, CPU usage with HIFN driver and acrypto is noticebly > less, since that setup is CPU limited for stock synchronous kernel > setup (3Ghz P4 with HT enabled). > Above numbers drift with the time, especially when machine running > stock FC4 kernel overheats, and that numbers decrease to 12-13 MB/s. > > One can find combined patchsets for 2.6.15 and 2.6.16 trees which > include acrypto with SW crypto provider, dm-crypt and IPsec engines > at acrypto homepage [1]. > > Credits. > Yakov Lerner for great testing and bug-hunting. > Michal Ludvig for original VIA padlock and fcrypt drivers. > > > Thank you. > > 1.
