Nas performance testing program

I've had this for over 10 years, will all of the original disks still working. This is basically just used as a backup target for all of the various home and office PCs and to store photos. This gets backup up to an off-site rotation HDDs. It works great, but is slow My replacement needs to be low-power J is currently at about 20 W idle, 25 W active and to offer a pool that can suffer one or two failures either raids or mirror. The system I've got here is mainly bits that I had lying about with a couple of extras e.

Just shows what some decent buffering in the client can do to help. Tracked down what was causing the differences between read and write speeds - for some reason the MTU on the client was set to over I ran some comparative tests on the ReadyNAS and got 40 for read, 20 for write.

Deleted member Apr 24, General Questions and Help. It is designed for testing network performance between two computers and is based on Winsock 2.

It measures ICMP response times and network transfer rates for different packet sizes and protocols. All results are stored in a SQLite database file and can easily be compared. The results of that comparison with the previous benchmark will indicate whether or not there really is a problem and dictate which steps to take next if any. Regardless of your technical expertise or how expensive your diagnostic tools are, if you are modifying a wireless network or making decisions to modify it and you are not testing throughput then you risk wasting time and resources going down the wrong path.

It supports tuning of various parameters related to timing, protocols, and buffers. For each test it reports the bandwidth, loss, and other parameters. These include, for example, a zero-copy mode and optional JSON output. Note that iperf3 is not backwards compatible with the original iperf. The software has been optimized to use a minimum amount of CPU time, allowing even high speed gigabit ethernet connections to be benchmarked. Users have the ability to change the following test parameters.

NPB 2 contains MPI-based source code implementations of the original eight benchmarks, and NPB 3 has included new benchmarks and problem classes as well as implementations using other programming models.

NPB 3. You may want to use a search engine to find relevant information on the internet. NAS is currently working on creating a more automatic archiving facility, as well as a tool for creating performance plots on the fly. They will be incorporated into a database maintained by NAS, and will also be made available on this web page. Send results to npb nas. Details on what information should be submitted are contained in appendix D of the NPB 2. This information includes:.

Vendors and others implement the detailed specifications in the original "pencil and paper" benchmark specifications, using algorithms and programming models appropriate to their different machines. Submitted results are verified by the NAS Division. These results are compiled in tabular fashion in periodic reports that will appear on this web page.
