rrdtool performance tuning

[Dmitry Morozovsky]

Dear colleagues,

any hints to tune rrdtool with ~30k rrd files (approx 2k target devices)?

machine is mostly IO-bound, showing 100% disk load with 8 or sometimes even 3 
mB/s, 300-400 tps (it's 2 SATA300 disks in gmirror)

Thanks in advance.

Sincerely,
D.Marck                                     [DM5020, MCK-RIPE, DM3-RIPN]
