dd: TEST Disk READ Speed The filetempfile, that has just been created by the previous command, wascached in a bufferand its read speed is much higher then the real read speed directly from the disk. To get the real speed, we have to clear cache. Run the following command to find out...
Sysbench is a command line utility program available on linux that can be used to conduct different types of benchmark tests to measure performance of disk io, memory, cpu and mysql database. In another article we learned how to use sysbench to test ram read/write speed. In this particular...
Direct drive read speed test withhdparm sudo hdparm -t /dev/sda This test returns timing buffered disk read speed and this result could be assumed as the fastest disk read speed. note:In Linux, it is common that native filesystems (ext4, btrfs, xfs etc.) always tends to perform better ...
If you need to troubleshoot an issue with slow Internet access on your Linux system, it would be a good idea tomeasure the current Internet speed. In this article you’ll find how totest Internet speed from the Linux terminal, usingspeedtest_cli– a simple command-line client written in P...
Looking at your write speed results, I suspect that your pendrive is also cached by the kernel. Reply mrh June 24, 2015 at 8:08 pm if dd command is used to monitor performance of a drive especially for a usb disk, conv=fsync should be set in order to flush the memory each time...
