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.
