Workload spike could cause IO performance problems. The underlying disk can not support this workload during that time and it leads to a very high disk utilization issue. Check disk IO usage by Process with iotop command in Linux Theiotop commandis top-like utility for looking at disk I/O...
In this article we will discuss how to check the performance of a disk or storage array in Linux.IOPS(input/output operations per second) is the number of input-output operations a data storage system performs per second (it may be a single disk, a RAID array or a LUN in an external ...
if=/dev/zero (if=/dev/input.file) Indicates the input file that you want to read using the DD command. of=/tmp/test1.img(of=/path/to/output.file) Indicates the output file that you want to write using the DD command bs=1G(bs=block-size) Indicates the size of the block that you...
In this tutorial, we’ll learn about the important metrics when considering disk performance. Additionally, we’ll look at some command-line tools in Linux that allow us to benchmark a disk device. 2. Disk Performance Testing the performance of a disk is crucial for understanding its capabiliti...
