ACFS performance

Hi all !

Doing some simple disk tests on our 4 ODA'as (X5-2,VP 12.2.1.4)

I'm curious if these figures are "normal" !?

We're experiencing a degradation in performance over time (3 yrs) ...

Test performed in ODA_BASE

Prod box:

Data/tbs disk

hdparm -t /dev/asm/cobra1p-470

Timing buffered disk reads: 352 MB in  3.01 seconds = 116.90 MB/sec

FRA disk

hdparm -t /dev/asm/datastore-140

Timing buffered disk reads: 298 MB in  3.02 seconds =  98.52 MB/sec
