Anyone using ZeusRAM for ZIL? What are your write/read performance for 4k random write?
I have a RaidZ2 pool with 10x4TB SAS drives and ZeusRAM for ZIL and when testing with fio, I only get around 2500iops, which is way too little I think.
I also tried creating a mirror pool with 2xZeusRAM, but system somehow gets limited, again, at 2,5kIOPS as well.
My drives are in a Supermicro JBOD with SAS expander and connected to LSI 9207 HBA. I will try with linux tomorrow, maybe it's an OS problem?
lp, MAtej
