dm-crypt performance and dual-core cpus?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

does anyone here have performance experience with dm-crypt running on dual-core vs. single-core systems?

I am currently using AES-128 encryption and am able to get about 31MB/s sustained performance on my single-core athlon 64 3000+ (when copying from the encrypted volume to a fast non-encrypted volume).

Since 31MB/s is will below the limits of gigabit ethernet, i would like to get even more performance :-)

Does anyone know if the AES encryption (or any other available encryption, I'm willing to swap if necessary) does profit from adding a second cpu (core) ?

Gerald
