It does not matter if I use jiffies in these cases where memory is limited

memory.limit_in_bytes = 4M
Responsiveness : Very good
Disk speed : 40% of disk capabillity
iowait : Generally around 50%

Responsiveness : Good

Interestingly I can't get the disk speed > 50% of the disk capabillity reported by hdparm, not event with oflag=direct

Eearlier I have reported that jiffies performed better, but that was without memory-limitations.
