Performance in Intel IOMeter FileServer and WebServer Patterns

Now it’s high time we ran some tests in server patterns. Keeping in mind the results obtained in the DataBase pattern, we do not expect much here, but still.

In FileServer pattern WD740GD is about 10% faster than the SCSI drives under linear workload. But as the workload increases, it starts falling behind them. In WebServer pattern WD740GD drive doesn’t boast any evident advantage over the SCSI competitors under linear workload: it can’t resort to its main weapon any more – the lazy write algorithms.

If we try to average out the HDDs performance under all types of workload we will get the following picture:

No doubt that WD740GD can successfully compete with SCSI drives only under low workload, and since the rating is calculated basing on the performance of our testing participants under five types of workload, WD drives do not look that attractive any more…
