Truecrypt 7.0 Linux AES-NI Benchmark
The new Truecrypt 7.0 release is almost 7 times faster compared to 6.0 on my i7-620M with AES-NI. It is some hundred mb/s faster now than dmcrypt (which runs my system-encryption on Debian Squeeze), but that is expected since truecrypt makes use of multiple cores AND aes-ni and dmcrypt only supports 1 thread per mounted device, so unless you create a RAID consisting of multiple dmcrypt-devices, you can only use 1 core.
Another nice thing, they ported the included benchmark-tool from windows to linux. In 6.3 there was no benchmarking when running under Linux, but now it is supported.
Truecrypt achieves between 1600 and 1700 mb/s. I ran the benchmark for 1mb, 5mb, 10mb, 50mb, 100mb and 1024mb, skipped 200mb and 500mb, because I was tooo lazy
