Hi,
Can anyone with access to Atom D525 processor can do a performance check for me:
# kldload geom_eli
# kldload geom_zero
# sysctl kern.geom.zero.clear=0
# geli onetime -s 4096 -l 256 -e aes-cbc gzero
# dd if=/dev/gzero.eli of=/dev/null bs=1m count=4096
# geli kill gzero
# geli onetime -s 4096 -l 256 -e aes-xts gzero
# dd if=/dev/gzero.eli of=/dev/null bs=1m count=4096
I'm interested in dd outputs ofcourse. I would like to compare this to
VIA Esther processor 1000MHz, which has padlock AES accelerator.
My results are:
AES-CBC:
4294967296 bytes transferred in 31.805894 secs (135036836 bytes/sec)
AES-XTS:
4294967296 bytes transferred in 765.232668 secs (5612629 bytes/sec)
Anyone can provide the results for Atom D525?
