AWS New I/O optimized I4i - Latency

Go back to list

IOPS represents well the performance reachable by a system but It has the defect of being an already calculated value hiding some aspect of performance. Where IOPS is rate, the latency expressed here aims to display the time taken for each I/O operation.

The exact same methology than for IOPS is used, we only report the average latency instead of IOPS.

Assertions

  • In terms of read, latency is quite correlated with IOPS.
  • Write performance gives a lead to i3en.
