Average Response Time

The average response time is the average amount of time a storage device takes to receive a data request, find the corresponding data, access it, and return the requested results. It depends on various factors, including network bandwidth, the number and type of data requests, the type and technical characteristics of the storage hardware, and the number of users performing these data requests. The results below assume the NAS is accessed by a single user only. Check the "Performance Summary with Multiple Clients" page for multi-client response time results.

Throughput

The following graph shows the overall throughput of the NAS in all tests we conducted using the DiskSpd tool in an OLAP scenario with QD4.



Some comparison graphs of the EXT4 and btrfs filesystems follow.

IOPS
