Benchmark Results: Iometer

Protect Your Data! TrueCrypt 7.0a's Performance, Analyzed
By , Achim Roos

The most interesting results come from our Iometer benchmarks.

Looking purely at the encryption, the AES-NI instruction set provides a consistent performance gain. And even if the performance gain is rather small, the CPU load is several times lower than in the conventionally-encrypted system. However, the encrypted systems are significantly slower than the unencrypted system, with or without hardware acceleration.
