...al performance gain
comparing to their existing systems. However the outputs of the I/O
stress test with iozone show the mixed results as follows:
* The read performance sharply degrades (almost down to 1/20, i.e
from 2,000,000 down to 100,000) when the file sizes are larger
than 256KBytes.
* The write performance remains good (roughly 1,000,000) even with
the file sizes larger than 100MBytes.
The NFS/ZFS server configuraion and the test environment is briefed as
* The ZFS pool for NFS is composed of the 6 disks in stripping with
one on each SATA controller....
