Hi, I'm new on this mailinglist and don't even know if it's the right one, but here is my problem: I'm running Debian Lenny and created a soft raid 5 there, with 6 Hard disks (each 750 GB). Now i did cryptsetup -c aes -s 128 /dev/md1 and cryptsetup luksOpen /dev/md1 data. Now, if I Benchmark with hdparm -t /dev/mapper/data, I don't get more than 80 MB/s (hdparm -t /dev/md1 gives about 280MB/s read speed). My CPU utilization is at 100% on both cores (It's an AMD 4200+, I'm running 2.6.23 amd64 kernel). So now my Question is: Is there a cheaper encryption method? So that i can get at least 120MB/s, 160 would be fine. I tried with -s 64, but it then tells me to check wether the aes-... module is in the kernel - but obvious it is, else 128 wouldn't work. If anyone would have a good suggestion to increase the speed, let me know. Thanks in advance, Theodor 'morphium' Reppe --------------------------------------------------------------------- dm-crypt mailing list - http://www.saout.de/misc/dm-crypt/ To unsubscribe, e-mail: dm-crypt-unsubscribe@xxxxxxxx For additional commands, e-mail: dm-crypt-help@xxxxxxxx
