hIOmon SSD Performance Monitor - Understanding desktop usage patterns.

[Ao1]

Here I capture Black Ops MP at the Device Level, Volume Level and File Level . All at the same time

The same map was reloaded around 5 times ~20 minutes. AV enabled.

I only started monitoring AFTER the fist map had loaded. Read xfers related to the first map load at the device level are therefore excluded, but available at the Logical Device Level for subsequent I/O's. (Assuming they were held in cache when the monitoring started).

Any read xfers (at the device level) are subsequently down to dropped cache or reads generated during game play. (Also any other background reads from the OS/ AV etc).

I hope I got that right. It seems to stack up with the highlights below.

Device Level Reads
• Data transferred = ~180MB
• Total I/O's = 1,645
• Max IOPs = 2.7
• FastIOPS 76.8 % (less than one millisecond).
• Min xfer size = 512. Average xfer size = 116,522. Max xfer size = 9,433,088. (~9MB)
• Min response time = 0.0451ms. Avg response time = 0.9008ms. Max response time = 50.154ms
• Maximum data transfer rate for a single I/O operation. = 268.315MB/s.

Logical Disk Reads
• Data transferred = ~3.7GB
• Total I/O's = 839,171
• Max IOPs = 1,502.8
• FastIOPS 97.4 % (less than one millisecond).
• Min xfer size = 2. Average xfer size = 4,973. Max xfer size = 9,957,376.
• Min response time = 0.0034ms. Avg response time = 0.0109ms. Max response time = 50.3104ms
• Maximum data transfer rate for a single I/O operation. = 2,898.44MB/s.
