Need to display current disk performance / capability

[diskdiddler]

Hi,

I forgot the command (sorry!) which lets me benchmark my pool.
I'm having some buffering issues, playing back some media to a Raspberry Pi, over 1Gbit eth (it's a Pi4)
It's working for 10/20/30 minutes at a time and then caching.
I'm fairly sure it's not the NAS but I'd like to elminate it by SSH'ing into the NAS and seeing what's going on with my media pool.

I know the problem can crop up during a scrub but alas, it was not a scrub.


Pretty sure there's a command to see how much bytes are currently being read from the pool at the time and or a command to show what the pool is generally capable of?
Anyone got some tips, please?

(Using top is not identifying a CPU issue and I'm not using plex, it's just over straight SMB)

gstat -dp will tell you the current stats as far as reads/second, IO rates, etc - for benchmarking "what a pool can do" that's a more complex issue.

Thanks for this, almost positive it's not the NAS now.

also zpool iostat 5 5 (interval, count) will give you 5 readings 5 second apart
