SAS1068E / MPT SAS / R300 VERY Very slow

[L.P.H. van Belle]

check this.
 
Same server DELL R300 XEN 4.1 Express 
[root at engine ~]# hdparm -tT /dev/sda
 
/dev/sda:
 Timing cached reads:   7608 MB in  2.00 seconds = 3806.45 MB/sec
 Timing buffered disk reads:  read(2097152) returned 1859584 bytes

try again.. within the minute..  
 
[root at engine ~]# hdparm -tT /dev/sda
 
/dev/sda:
 Timing cached reads:   7240 MB in  2.00 seconds = 3622.54 MB/sec
 Timing buffered disk reads:  106 MB in  3.34 seconds =  31.75 MB/sec


Im wondering what dell is going to do about these problems with the 
SAS1068E PCI-Express Fusion-MPT SAS (rev 08) controllers
 
 
 
Ow and on this XEN Express servers were 2 guest running but these where just
test
servers doing nothing.
