I just installed OpenBSD for the first time on my computer yesterday and I have some questions.
1) I installed mpd and ncmpc for music, and I used libao in the mpd.conf. The problem is that songs are generally playing too fast. Some of them sound like chipmunks singing. Has anyone experienced this? I looked through the openbsd documentation, but I could not find any specific setup/fix. I tried playing with audioctl, but I can't seem to change any values.
(Not sure if this is connected to the next problem)
2) I have 4 hard drives on my computer, so I used one for root partition, and setup RAID5 with the other three using softraid. I copied my backed up files from my laptop through nfs and scp, but it took almost a whole day to copy the data (connected through LAN). So, I tried benchmarking the disk io performance using bonnie++ and the results are:

Not too sure how to interpret these numbers. If anyone has some data to compare, it would be very helpful.
