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? Cheers, Wiktor Niesiobedzki
