Getting this with pveperf on RAID 10 with BBU and writeback and 6x 1TB Enterprise HDD Sata disks

CPU BOGOMIPS: 57595.92
REGEX/SECOND: 1879039

Buffered reads is low
But using hdparm get this:
/dev/sda:
Timing cached reads: 18112 MB in 2.00 seconds = 9064.94 MB/sec
Timing buffered disk reads: 862 MB in 3.00 seconds = 287.30 MB/sec
root@vz-cpt-1:~# hdparm -Tt /dev/sda
/dev/sda:
Timing cached reads: 17966 MB in 2.00 seconds = 8991.92 MB/sec
Timing buffered disk reads: 1132 MB in 3.00 seconds = 376.88 MB/sec
Anything to worry about?
