Performance in Intel IOMeter: FileServer and WebServer Patterns

FileServer and WebServer patterns were used to test hard disk drives in the environment typical of storage subsystems in file- and webservers.

Let’s see what results the hard disk drives show in the FileServer pattern. WD2500PD appears to be somewhat faster. Its advantage over the rival grows even bigger as the number of requests in the queue increases.

The diagram shows integral performance ratings of the testing participants, equal to average requests processing speed under all sorts of workload. WD2500PD HDD is not dramatically faster than the opponent but its advantage is still evident in both cases.

The results of our tests in the webserver pattern suggest that WD2500SD should be regarded as the winner. The diagram also shows that this hard disk drive appears faster than WD2500PD regardless of the requests queue depth.

As you remember, WD2500SD was faster than the opponent in DataBase pattern when we had random reading requests. Therefore, it is not at all surprising that  in WebServer pattern these drives feel perfectly at home.

On the diagram with overall performance indexes, which we calculated the same way as in the previous case, we see an evident victory of WD2500SD HDD.
