Performance in Intel IOMeter File Server and Web Server Patterns

We compare the arrays by averaging their performance at the four loads.

This time TCQ positively affects the performance of the arrays in the pattern. The average speed has grown up everywhere, which is especially conspicuous with the RAID0 arrays. As you understand, the minor loss at small loads is compensated by the bigger speed gains at high loads here.

Let’s see now what we have in the Web Server pattern.

There’s a little more red color in the table of efficiency. Take a look at the diagram:

The diagram looks fine: enabled TCQ most positively affects the performance of the arrays.
