Mit einem Tool namens Lighthouse kann die Performance einer Website insbesondere für mobile Endgeräte analysiert und gemessen werden. LIghthouse ist in Google Chrome integriert, kann aber auch als NodeJS modul installiert und programmatisch ausgeführt werden. |
|
Update: Seit #17 wird immerhin die Antwortzeit des Server erfasst und ausgegeben und fließt mit in das Ranking ein. |
|
Update: Lighthouse läuft "headless" in einem Docker-Container und schreibt als Ergebnis eine JSON-Datei. Sehr schön. Allerdings funktioniert es nicht mit allen URLs. Es scheint einen Fehler im JavaScript-Code von Lighthouse zu geben. Und wenn es funktioniert, dauert es eine ganze Weile (etwa 40 Sekunden). Dockerfile: FROM debian:stretch

Das Problem war offenbar zu wenig Swap-Speicher bzw. zu wenig Platz in /dev/shm im Docker Container. Es funktioniert, wenn man ein Volume mountet: |

Mit https://github.com/giantswarm/lighthouse hätten wir ein Docker-Image für Google Lighthouse, das für die Durchführung der Performance-Tests genutzt werden kann. |
|
Tests mit Lighthouse bringen zwar sehr umfangreiche Ergebnisse. Sie erfordern aber auch, jede URL noch ein weiteres Mal abzurufen. Das vergrößert den Aufwand für das Spidern erheblich. Als Alternative habe ich das Performance Logging in Chrome aktiviert. Damit lässt sich das Ladeverhalten schon sehr detailliert auswerten. Experimentell habe ich bislang zwei Metriken erfasst:
Hier einige Auswertungen.
Die beiden letzten Graphen scheinen anzudeuten, dass es geradezu eine Mindestmenge sowohl für die HTTP-Anfragen als auch für die übertragene Datenmenge gibt. Das könnte man noch genauer auswerten und beispielsweise mit Lighthouse ausloten, welche Optimierungen noch bei den besten Sites vorgeschlagen werden. Dann stellt sich die Frage, wie man die beiden Metriken mit Punkten versehen möchte. Übrigens möchte ich im Moment davon absehen, die tatsächliche Ladezeit als Metrik heranzuziehen. Grund dafür ist, dass der Spider häufig auf einem Computer mit DSL-Anbindung ausgeführt wird und die Ladezeiten davon negativ beeinflusst werden und stärker schwanken. Sollten wir eines Tages wieder auf Server-Infrastruktur mit hoher Bandbreite spidern, kann sich das ändern. |
