    Yes, your hard disk read and write response time is higher than recommended .025 ms threshold . Ideally less than .015 is recommended however when things are pretty busy .025 is the number you should be looking at. If it’s more than that then things starts getting impacted

  • 10 miliseconds is the great number to have best performance.

    it’s almost on the edge of too bad. Greater than 25 is considered as serious performance problem

  • sorry, but i wanna to clarify a matter here: Latency which analyses by PAL is in VM, latency in physical got a bit differ. So what latency is best indicator to track performance ?

    I think both since, both depend on each other
