Disk mark performance test5/21/2023 ![]() Volume storage can be fast but not as fast as ephemeral storage. This storage is highly redundant, your data is stored three times on different machines. The volume is a remote attached block device, the data on this storage type is stored on our storage cluster. Every flavor can have a different size ephemeral storage with different speed limits which you can find in our dashboard. If you however deploy your operating system on a volume your system will not have an ephemeral disk attached. This is the fastest storage we offer and the best is it comes for free with your instance. The ephemeral storage is provided by local fast, low-latency NVME drives. If your system can do more simultaneous transactions your applications will spend less time waiting for io transactions.įuga has several different block device options. Your operating system usually has a queuing system for this. If your disk can do just one operation at a time, only one application can use the disk and other processes will have to wait. Especially for multi-threaded applications, it's the IOPS metric that's important. Every disk operation can be either a read or write action with specific data size. ![]() We use input output operations per second or IOPS. The disk performance can be expressed in different metrics. Additional volumes must be manually formatted and mounted. The disk is usually formatted with an ext4 filesystem and mounted as '/'. ![]() It will be available in the "/dev" folder as "/dev/vda", "/dev/vdb" and so on. Other benchmarksĪ disk in Fuga is a block device presented in your VM. You can repeat these tests on any similar platform and compare the results. We will use an Ubuntu VM and test the Disk. ![]() How to do a Disk benchmark test We will explain how you can test and compare the performance of our instance flavors. ![]()
