Benchmarking is the process of simulating different workloads on your application and measuring the application performance for each workload. Using the steps described in the designing for high performance article, you have gathered the application performance requirements. By running benchmarking tools on the VMs hosting the application, you can determine the performance levels that your application can achieve with premium SSDs. In this article, we provide you examples of benchmarking a Standard_D8ds_v4 VM provisioned with Azure premium SSDs.

We have used common benchmarking tools DiskSpd and FIO, for Windows and Linux respectively. These tools spawn multiple threads simulating a production like workload, and measure the system performance. Using the tools you can also configure parameters like block size and queue depth, which you normally cannot change for an application. This gives you more flexibility to drive the maximum performance on a high scale VM provisioned with premium SSDs for different types of application workloads. To learn more about each benchmarking tool visit DiskSpd and FIO.

To follow the examples below, create a Standard_D8ds_v4 and attach four premium SSDs to the VM. Of the four disks, configure three with host caching as "None" and stripe them into a volume called NoCacheWrites. Configure host caching as "ReadOnly" on the remaining disk and create a volume called CacheReads with this disk. Using this setup, you are able to see the maximum Read and Write performance from a Standard_D8ds_v4 VM. For detailed steps about creating a Standard_D8ds_v4 with premium SSDs, see Designing for high performance.

The disk with ReadOnly host caching is able to give higher IOPS than the disk limit. To get this maximum read performance from the host cache, first you must warm up the cache of this disk. This ensures that the Read IOs that the benchmarking tool will drive on CacheReads volume, actually hits the cache, and not the disk directly. The cache hits result in more IOPS from the single cache enabled disk.

Download the DISKSP tool on the VM. DISKSPD is a tool that you can customize to create your own synthetic workloads. We will use the same setup described above to run benchmarking tests. You can change the specifications to test different workloads.

FIO is a popular tool to benchmark storage on the Linux VMs. It has the flexibility to select different IO sizes, sequential or random reads and writes. It spawns worker threads or processes to perform the specified I/O operations. You can specify the type of I/O operations each worker thread must perform using job files. We created one job file per scenario illustrated in the examples below. You can change the specifications in these job files to benchmark different workloads running on Premium Storage. In the examples, we are using a Standard_D8ds_v4 running Ubuntu. Use the same setup described in the beginning of the benchmark section and warm up the cache before running the benchmark tests.

We use four worker threads for driving Write operations and four worker threads for driving Read operations on the disks. The write workers are driving traffic on the "nocache" volume, which has three disks with cache set to "None". The read workers are driving traffic on the "readcache" volume, which has one disk with cache set to "ReadOnly".

While the test runs, you are able to see the number of write IOPS the VM and Premium disks are delivering. As shown in the sample below, the Standard_D8ds_v4 VM is delivering its maximum write IOPS limit of 12,800 IOPS.

While the test runs, you are able to see the number of read IOPS the VM and Premium disks are delivering. As shown in the sample below, the Standard_D8ds_v4 VM is delivering more than 77,000 Read IOPS. This is a combination of the disk and the cache performance.

While the test runs, you are able to see the number of combined read and write IOPS the VM and Premium disks are delivering. As shown in the sample below, the Standard_D8ds_v4 VM is delivering more than 90,000 combined Read and Write IOPS. This is a combination of the disk and the cache performance.

In that article, you create a checklist similar to your existing application for the prototype. Using Benchmarking tools you can simulate the workloads and measure performance on the prototype application. By doing so, you can determine which disk offering can match or surpass your application performance requirements. Then you can implement the same guidelines for your production application.

I have numerous hard drives and i figure i should benchmark them every so often because that's what websites tell me to do. But i'm worried if using the stock "Disks" utility that comes with Ubuntu 16.04 desktop will affect any data already on the drives. There is only one option "Start Benchmark", so it's not like i have any useful information to work from.

I suppose it's a multi-pronged question:

Is it safe to benchmark a drive with stuff already on it? If so, is it also safe if that drive is being accessed by the system for whatever reason, or should i make sure nothing else is accessing that drive first? should i dismount them first (and i suppose, can i benchtest an unmounted drive?), and finally, do i really need to do these every month or so as some sites are suggesting; they aren't as trustworthy (to me) as askubuntu, and i've always valued the opinion of the people in this group.

PassMark Software has delved into the thousands of benchmark results that PerformanceTest usershave posted to its web site and produced four charts to help compare the relative performance ofdifferent hard drive models with storage capacities from gigabyte to terabytes.

Our chartsinclude results from many major hard drive manufacturers, including but (not limited to)Seagate, Western Digital (WDC), Hitachi, Maxtor and Samsung. Our data can help you assess theperformance of your hard disk drive (HDD) in comparison to similar models, or help you decidewhether newer hard drive technologies (such as solid state hard drives) represent good value foryour purchasing dollar when it comes to high performing data storage and retrieval.

I was having a really hard time getting any benchmark to run on Windows 95 (RTM version, oldest). Roadkill's disk benchmark, HD tach, SiSoft Sandra 99 and 01 all crash with various DLL or page fault errors. The only thing that worked for me was SiSoft Sandra 98 (somewhat hard to find. Found it on this cd, direct download from inside the ISO here (filename SiSandra.exe). Install it and choose "Drives benchmark".

I've already submitted a Synology Support Ticket but the response I got was to start testing my hard disks on a computer using manufacturer provided tooling. (As in, they didn't read my ticket at all)

For those unaware, GNOME has a really nifty tool called gnome-disk-utility which can format, partition, backup, restore and even benchmarks all kinds of storage. I love it os much that even on my KDE installs I use it.

I'm trying to find out why my application is very slow on a certain machine (runs fine everywhere else).I think i have traced the performance-problems to hard-disk reads and writes and i think it's simply the very slow disk.

And look especially at the queue-counters. A disk can be very fast ad sequential reads, but as soon as it tries to access the disk simultaneously the queue might peak and give you horrible performance.

This Advanced Disk Test, which is part of PerformanceTest, measures the data transfer speed when reading or writing data to one or more disks. The speed that data can be transferred between memory and a hard disk drive is one of a system's most important performance aspects. There are quite a few factors which have a bearing on this speed and the Advanced Disk Drive Test allows the user to vary most of these factors and compare the results.

Users have the ability to select the disk drive for testing, file size, the units of measurement, test duration, sample frequency and test iterations. When selecting Run All, the test will run through a series of ten preset tests. Results and associated graphs to be exported as HTML.

Whilst the loader versions 'may' make a difference, it's more likely to be the CPU hardware that dictates CPU performance. Disk Controllers and Disk types are also more likely to dictate disk performance (funnily enough)..

As long as people list their hardware relevant to the benchmarks (ie CPU, disk controllers and disks etc - along with the loader versions) it should be good enough to find out where any problems might lie..

Disk Benchmark performance measurement tool is frequently used to test any manufacturers RAID controllers, storage controllers, hard drives and SSD. MiniTool Partition Wizard makes disk benchmarking rather easy.

Benchmarking has been a popular way to test disk speed for years. It is the process of running software to measure the transfer speeds under various disk access scenarios like sequential and random, and showing the results in MBps that summarize the speed characteristics of a disk. e24fc04721
