I had already ruled out the application as a possible cause of the pauses however @jlliagre's wise words forced my to take another look. Embarrassingly i was barking up the wrong tree and the app was to blame. Thanks everyone one and sorry to take up your time.

I would like to stress the performance WAS very good until recently when it started pausing every minute. Inbetween the pauses the performance is great. zfs list NAME USED AVAIL REFER MOUNTPOINT data01 2.98T 1.71T 42.0K /data01

The server has 64 gb ram. The cache hit ratio is fairly poor so we have decided not to use an L2ARC.

The zpool contains 12 ssd's in raidz-1 configuration. The load is made up of a large number of small random reads.
