Orion 11.2 Small Read Latency meaning

Hi all,

I am using Orion to measure performance of our new storage solution. In the summary output I get something like that:

Maximum Small IOPS=3620 @ Small=360 and Large=0
Small Read Latency: avg=99435 us, min=23698 us, max=712720 us, std dev=51360 us @ Small=360 and Large=0

Minimum Small Latency=53431 usecs @ Small=20 and Large=0
Small Read Latency: avg=53431 us, min=397 us, max=661723 us, std dev=46843 us @ Small=20 and Large=0

Could any one give me some feedback abuot hthe meaning of each parameter of the "Small Read Latency"

Thank you in advance., regards
