Re: softraid crypto performance on Sun Fire T1000

Ah, thanks. I was just about to destroy my RAID-1 and see it that makes a difference :). So, the difference is pretty much the kernel locking: The fewer cores, the better the performance. But this still means that the softraid crypto performance is way below what openssl speed gives. I wonder if

Another thing I noticed: When running dd if=/dev/zero of=foo bs=65536, my SSH connection gets extremely laggy. If I open 4 more in parallel, all go down to KB/s of writes, and SSH becomes unusable. Now unusable as in things need forever to start. Unusable as in I press a key and it takes forever

softraid crypto performance on Sun Fire T1000

Hi! I just installed OpenBSD 6.0 on my Sun Fire T1000 (with 2 SAS HDs in a hardware RAID 1 that I set up from OpenBoot). However, I only get read rates of less than 2 MB/s from sd1a (the softraid), but reads from sd0d (the underlying partition of the softraid) get magnitudes more. While a single

Bonnie is not a realistic load, ever. Therefore the numberis are really not useful. If one insists on getting an idea of what crypto can run then do: dd if=/dev/rsd2c of=/dev/null bs=1m count=100 Where rsd2c is the raw crypto disk. At some point I will have another look to see if I can speed it

, it looks like my server's softraid crypto performance is pretty good, especially when taking into account that softraid(4) and the crypto discpline are very new to OpenBSD. One curious result is that my read speeds are lower than write. I was expecting reads to be a lot faster since the crypto
