Note: One should run the above command 2-3 times and manually average the results for an accurate evaluation of read speed, per hdparm(8) § T. Timing buffered disk reads: x MB in y seconds = z MB/sec Timing cached reads: x MB in y seconds = z MB/sec This method is independent of partition alignment! Using hdparm with the -Tt switch, one can time sequential reads. Storage media can be benchmarked with hdparm ( hdparm). time contains the time command and some shells provide time as a builtin command. The time(1) command provides timing statistics about the command run by displaying the time that passed between invocation and termination. Iperf can be installed, or a different version of iperf is available with iperf3. It has nicely formatted output and a parallel test mode.
Iperf is an easy to use point-to-point bandwidth testing tool that can use either TCP or UDP. Various flavors of ttcp can be found in the AUR: The program must be provided on both nodes between which bandwidth is to be determined. Ttcp (Test TCP) measures point-to-point bandwidth over any network connection. Interbench is available in the AUR: interbench AUR. Tip: With careful benchmarking, different hardware can be compared. It is designed to measure the effect of changes in Linux kernel design or system configuration changes such as CPU, I/O scheduler and filesystem changes and options. Interbench is an application designed to benchmark interactivity in Linux. Install unixbench AUR, to run the benchmark run ubench. Many tools can be used to determine system performance, the following provides a list of tools available. What driver version should be used to get optimal performance?.This unified method of evaluating system performance can help answer questions such as: Benchmarking is the act of measuring performance and comparing the results to another system's results or a widely accepted standard through a unified procedure.
