|
# host: <captured per run> suite v3 portable kit
|

#
|
|
|
|
|
# Target: a stock Fedora 44 with internet. Missing tools are installed via dnf
|
|
|
|
|
# (INSTALL_DEPS=1). Specs are captured with ./capture-specs.sh, not hardcoded.
|
|
|
|
|
#
|
|
|
|
|
# Purpose: measure a hardware upgrade with an identical, repeatable set of
|
|
|
|
|
# tests on both sides — capture the AFTER run once the new build is up.
|
|
|
|
|

# Quick path (run-benchmarks.sh is split; see README):
|
|
|
|
|
# headless: ./run-benchmarks.sh before headless # over SSH (ssh -t)
|
|
|
|
|
# headed: ./run-benchmarks.sh before headed # in the desktop session
|
|
|
|
|
# repeat both with "after" post-swap; tags become before-headless / before-headed
|
|
|
|
|
# This file is the reference for what that script runs, plus extras.
|

=> ground rule wants MEDIAN OF 3 runs: x3 the above
|
|
|
|
|
* powerlog.py samples power/temp ~1/s for the WHOLE part ->

|
|
|
results/power-<tag>.csv + results/phases-<tag>.csv
|
|
|
|
|
|
|
|
|
|
== GROUND RULES FOR A FAIR BEFORE/AFTER ==
|
|
|
|
|
1. Same OS image + kernel + mesa + tool versions on both runs. Record them.
|
|
|
|
|
2. Same storage drive in both runs (the WD Blue SN570). Same filesystem/options.
|
|
|
|
|
3. Same GPU, same driver, same displays, same resolution/refresh. Record which
|
|
|
|
|
GPU drives the displays (iGPU vs dGPU) — it changes between platforms.
|
|
|
|
|
4. Kill background load: close browsers, stop docker and VMs.
|
|
|
|
|
sudo systemctl stop docker docker.socket
|
|
|
|
|
5. Pin CPU governor to performance for timed runs (BEFORE default = powersave):
|
|
|
|
|
sudo cpupower frequency-set -g performance
|
|
|
|
|
# fallback if no cpupower:
|
|
|
|
|
for f in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor; do \
|
|
|
|
|
echo performance | sudo tee "$f" >/dev/null; done
|
|
|
|
|
run-benchmarks.sh does this AND restores the original governor on exit.
|
|
|
|
|
To measure another profile, set GOVERNOR= (the value is appended to the tag):
|
|
|
|
|
GOVERNOR=powersave ./run-benchmarks.sh after headless -> after-powersave-headless
|
|
|
|
|
GOVERNOR=performance ./run-benchmarks.sh after headless -> after-performance-headless
|
|
|
|
|
6. Warm up once, then take the MEDIAN of 3 runs. Throw away the first.
|
|
|
|
|
7. Note room/ambient temperature next to thermal results; thermals are noisy.
|
|
|
|
|
8. Use the SAME tool versions on both sides (with their (point) releases:
|
2026-09-29 21:21:06 -04:00
|
|
|
PassMark PT build). Record them in env-$TAG.txt.
|
2026-09-29 21:06:24 -04:00
|
|
|
9. BACK UP before any reinstall / reimage:
|
2026-09-29 21:21:06 -04:00
|
|
|
~/basic-benchmark/results/
|
|
|
|
|
copy it somewhere safe (off the machine) before reinstalling.

== HOW TO READ THE DELTA (not a benchmark) ==
|
|
|
|
|
- The BEFORE run is the control; the AFTER run is captured on the newly
|
|
|
|
|
installed system with this exact suite. Do not pre-fill after-specs.
|
|
|
|
|
- PassMark CPU Mark scales with core count; PassMark "CPU Single Threaded"
|
|
|
|
|
isolates IPC/clock. Read them together.
|
|
|
|
|
- Compare single-thread and all-thread CPU results separately: thread
|
|
|
|
|
counts differ between platforms, so total throughput alone can mislead.
|
|
|
|
|
- Compare memory bandwidth and latency independently; PassMark Memory Mark
|
|
|
|
|
also rewards the larger capacity.
|
|
|
|
|
- Components carried over unchanged (same SSD, same dGPU, same displays)
|
|
|
|
|
should land near-flat; a big move there means a setup fault, not a win.
|
|
|
|
|
- Compare idle vs load thermals and sustained clocks to judge the cooler.
