Hi guys,
I know there are a lot of thread with same question, but I don't solve mine,
I have freenas installed, and since yesterday pool was composed by
4 x4tb wd red + intel SSD d3-s4610 -480gb SLOG and samsung 850 evo 500gb as Cache
i decided to upgrade to 4 x d3-s4610 and delete slog and cache,
freenas via NFS is connected to HP dl80 gen 9 with ESXI 6.5 inside
VM on are 2012 server as DC
+ 2016 as RDS
after upgrading, performance are remained the same.
using Crystaldiskmark i obtain always same results
i'm not interested in sequential reading and writing because there bottleneck is the NIC 1gb
but obtaining 8MB in RND4K, i think is not enough
i tried with Sync = standard - = always - off
and result increase, but not as I thought
If i test the same in my samsung tablet, i obtain better performance
here my hardware
Freenas
mainboard gigabyte B250M-DS3H-CF
processore: i3 7100
ram: 64gb ddr4 2400mhz
controller LSI 9211-8I with firmware upgraded (IT)
case rack fantec with 8 hot swap bay
HP server DL80 gen 9
processor: e5 2603v3
48gb ram ECC
after many test i tried to install one test VM directly inside Freenas, with VM Disk inside the SSD Pool,
I increase the sequential read to 520 MB/s and write to 450MB/S
but Random read and write remain to 8/10MB
can someone help me to understand where is the bottleneck?
i'm so frustrated of testing and re-testing without any difference,
thank you
merry christmas!
and stay safe!
