Contrary to OP: AES-NI I did the test that is descripted on this page: http://wiki.debianforum.de/Benchmark_f%C3%BCr_Festplattenverschl%C3%BCsselung (Extended to 10GiB instead of the described 512MiB) My computer (Core i7 3770): does: 10735321088 bytes (11 GB) copied, 9.62266 s, 1.1 GB/s 10735321088 bytes (11 GB) copied, 9.71015 s, 1.1 GB/s 10735321088 bytes (11 GB) copied, 9.67001 s, 1.1 GB/s 10735321088 bytes (11 GB) copied, 9.61184 s, 1.1 GB/s 10735321088 bytes (11 GB) copied, 9.79301 s, 1.1 GB/s 10735321088 bytes (11 GB) copied, 9.96204 s, 1.1 GB/s 10735321088 bytes (11 GB) copied, 9.59942 s, 1.1 GB/s 10735321088 bytes (11 GB) copied, 9.61019 s, 1.1 GB/s 10735321088 bytes (11 GB) copied, 9.72707 s, 1.1 GB/s 10735321088 bytes (11 GB) copied, 9.88943 s, 1.1 GB/s So it's between 1066.52 MiB/s and 1027.7 MiB/s While the test is running, one core is @100%, the other 3 @50% (The 4 HT-Cores aren't used) so there is a bottleneck somewhere and this isn't the theoretical maximum. Bis denn -- Real Programmers consider "what you see is what you get" to be just as bad a concept in Text Editors as it is in women. No, the Real Programmer wants a "you asked for it, you got it" text editor -- complicated, cryptic, powerful, unforgiving, dangerous. _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx http://www.saout.de/mailman/listinfo/dm-crypt
