Re: Re: Re: low disk performance

other example:

rsyncing from/to the same zpool: 

device       r/s    w/s   Mr/s   Mw/s wait actv  svc_t  %w  %b 
c6            25.0  276.5    1.3    3.8  1.9 16.5   61.1   0 135 
sd44         6.0  158.3    0.3    0.4  1.9 15.5  106.2  33 [b]100[/b] 
sd45         6.0   37.1    0.3    1.1  0.0  0.3    6.5   0  10 
sd46         8.0   42.1    0.4    1.1  0.0  0.4    7.3   0  15 
sd47         5.0   39.1    0.3    1.1  0.0  0.3    7.3   0  10

sd44 is always at 100, performance are really really low ..
Using 3 lun or 4 lun in the zpool is the same.

any suggest?
