Try
blockdev --setra 4096 /dev/name
where 4096 is 4mb. this is a read ahead value.
I think my problem at times might just be the 100mbit network now. With
3 remote front ends. The back end is my desktop pc.
Also I rather let mythtv write often. I have already had 600gb of
recordings end up in lost+found. I only managed to get the names back
after I noticed the file sizes in the database.
