Benchmarking

CPU

Measures processing power by running CPU-intensive tasks. Tools like sysbench or stress can stress-test the CPU.

• Example using sysbench:
  📋

  sudo apt-get install sysbench  
  sysbench --test=cpu --cpu-max-prime=20000 run
  

Memory

Evaluates memory bandwidth and latency using tools like memtest86 or stress-ng.

• Example using stress-ng:
  📋

  sudo apt-get install stress-ng  
  stress-ng --vm 2 --vm-bytes $(awk '/MemFree/{printf "%d\n", $2 * 0.9;}' < /proc/meminfo)k --vm-keep -t 60s
  

Disk

Measures disk I/O performance using tools like fio or hdparm.

• Example using fio:
  📋

  sudo apt-get install fio  
  fio --filename=/dev/sdX --direct=1 --rw=randread --bs=4k --size=1G --numjobs=1 --runtime=60 --time_based --group_reporting --name=test
  

Network

Assesses network throughput and latency using tools like iperf.

• Example using iperf:
  📋

  # On the server side:  
  iperf -s  
  
  # On the client side:  
  php  
  iperf -c <server_ip>
  

GPU

Evaluates graphics rendering performance using graphical benchmarks like glxgears.

• Example:

glxgears

Power Consumption

• powertop
  • powerstat 1 10
    • cpu power monitoring
    • /sys/class/power_supply (laptops)

• Power Topology
  • Example:
    📋

    apt-get install sysbench stress-ng fio --all  
    sysbench --test=cpu --cpu-max-prime=20000 run stress-ng --vm 2 --vm-bytes $(awk '/MemFree/{printf "%d\n", $2 * 0.9;}' < /proc/meminfo)k --vm-keep -t 60s
    

This structure organizes the information into clear sections, making it easy to navigate and understand each component's performance evaluation.
