Hoping someone can give some pointers to improve write performance.

I have TrueNAS scale installed on PowerEdge R730XD server
Dual Intel Xeon E5-2680v4 processors (HT disabled) with total 28 cores.
256GB SK Hynix 32GB DDR4 2400MHz ECC RAM
PowerEdge server is connected to 2 x Seagate EXOS X 5U84 block storage connected via single HBA 9500-16e adapter.
Each Storage unit consists of 84 x Seagate 20TB SAS 4k 12Gbps HDDs (ST2000NM002D)
Created a single pool on each storage - With 6 x RAIDZ3 VDEVs Each VDEV consists of 14 x 20TB drives.
Have set a log ssd(735GB) device and also metadata device (735GB SSD) for this pool.
The purpose of this TrueNAS is to use it for backing up PB data from Isilon.Data consists of several small files adding upto PB storage.
