Performance in Intel IOMeter Fileserver and Webserver Patterns
Here we will take a look at the performance or RAID 0 and 1 arrays built with four different controllers and loaded as if they were typical file and web-servers.
Let’s start with the RAID 0 array working in the File-Server pattern.
On the diagram below we see that starting from queue=4 Intel controllers manage to get significantly ahead of the competitors. The best here is Intel ICH6R. SiS964 and VIA VT8237 do not yield to their opponents under linear workload, but then they get significantly more efficient when the queue grows up to 16 requests. VIA VT8237 controller is a little bit faster than SiS964, but as the number of requests in the queue grows up the advantage diminishes.
On this diagram we see the performance ratings for the tested controllers calculated as an average requests processing speed for different types of workload. Here we can clearly see how far ahead Intel’s solutions actually are. As for the performance differences between SiS964 and VIA VT8237, they are running really close to one another, the latter being just a little bit faster all the time.
When we have a RAID 1 array working in File-Server pattern we once again see how greatly Intel controllers outperform those from SiS and VIA. This advantage becomes evident starting with queue=4. Again ICH6R is faster than its predecessor. And SiS964 goes evenly with VIA VT8237 all the time.
The performance rating diagram shows how far ahead Intel controllers are and indicates equal efficiency of SiS and VIA products under this type of workload.
