PyPerformance

The Python Performance Benchmark Suite

Latitude 7490

Latitude 7490 runs Python 3.10.12.

Installed python 3.12 with headers:

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update
sudo apt install python3.12 python3.12-dev

Then install pip:

wget https://bootstrap.pypa.io/get-pip.py
python3.12 get-pip.py

verify:

> pip3 --version
pip 24.1.1 from /home/alex/.local/lib/python3.12/site-packages/pip (python 3.12)

Install pyperformance:

python3.12 -m pip install pyperformance

System Configuration:

> python3.12 -m pyperf system
Show the system configuration

System state
============

CPU: use 8 logical CPUs: 0-7
Perf event: Maximum sample rate: 100000 per second
ASLR: Full randomization
Linux scheduler: No CPU is isolated
CPU Frequency: 0-7=min=400 MHz, max=4200 MHz
CPU scaling governor (intel_pstate): powersave
Turbo Boost (intel_pstate): Turbo Boost enabled
IRQ affinity: irqbalance service: active
IRQ affinity: Default IRQ affinity: CPU 0-7
IRQ affinity: IRQ affinity: IRQ 0-19,47,51,120-121,127,138,149=CPU 0-7; IRQ 122=CPU 1,5; IRQ 123=CPU 2,6; IRQ 124=CPU 3,7; IRQ 125,136,142=CPU 7; IRQ 126=CPU 0,4; IRQ 128,134,140-141,144-147=CPU 5; IRQ 129=CPU 0; IRQ 130,139=CPU 1; IRQ 131,137=CPU 2; IRQ 132=CPU 3; IRQ 133,143=CPU 4; IRQ 135,148=CPU 6
Power supply: the power cable is plugged

Advices
=======

Perf event: Set max sample rate to 1
Linux scheduler: Use isolcpus=<cpu list> kernel parameter to isolate CPUs
Linux scheduler: Use rcu_nocbs=<cpu list> kernel parameter (with isolcpus) to not schedule RCU on isolated CPUs
CPU scaling governor (intel_pstate): Use CPU scaling governor 'performance'
Turbo Boost (intel_pstate): Disable Turbo Boost to get more reliable CPU frequency

Run "python3.12 -m pyperf system tune" to tune the system configuration to run benchmarks

Tuning was NOT done to preserve the power efficiency of the laptop.

Run performance test:

pyperformance run --python=/usr/bin/python3.12 -o latitude.json

Thinkpad P52

Thinkpad P52 runs Python 3.10.12.

Installed Python 3.12.2 using pyenv, then:

alex@p52 > ~/Projects/pyperf > pyenv versions
  system
  3.12.2
* 3.12.4 (set by /home/alex/Projects/pyperf/.python-version)

and

alex@p52 > ~/Projects/pyperf > python --version
Python 3.12.4

Install pip for python 3.12:

wget https://bootstrap.pypa.io/get-pip.py
python get-pip.py

verify:

alex@p52 > ~/Projects/pyperf > python -m pip --version
pip 24.1.2 from /home/alex/.pyenv/versions/3.12.4/lib/python3.12/site-packages/pip (python 3.12)
