this makes no sense, you are loosing about 12% of i/o capability here - 
even before hitting drbd, and then taking another hit on whatever drbd 
brings in ( depending on how its setup, even on a gigabit link that drbd 
load factor can be upto another 15 - 20%, or as low as 2 - 5% )

Again, not very clear. Do onething, post some real stuff, eg the proc 
status files for drbd and pvdisplay,gvdisplay and the raid status files 
( whatever raid setup you are using ).
