Hi everyone here
I have my own Truenas core server in the office.
Truenas core 13.0 u2
xeon 1620v3
64GB reg ecc ddr4
24*8TB HGST HDD
2TB nvme L2ARC cache and without SLOG(because I dont have best device for SLOG)
6 x Intel x520 10Gb network link to PCs without switch.
set sync=disable (for best write speed)
I upload 100GB file to the server, after that read speed drop down to even 2MB/S-10MB/S(normally should 700MB-1GB/S), then I restart the server and back to normal.
Why its happen and what should I do to fix it. Thanks a lot.
I remember the webgui have some settings about limit how much ram for write cache, Maybe I should do somthing there?
