Das WordPress-Plugin autoptimize soll für schnellere Ladezeiten und bessere Performance der WordPress-Seite sorgen. Um dies zu erreichen, werden alle Javascripte und CSS Dateien zusammengefasst und minifiziert.
Aber macht das in Zeiten von HTTP/2 eigentlich Sinn? Durch die Bündelung von mehreren Anfragen an den Server sollte es eigentlich keine großen Unterschiede machen, ob nun eine oder zehn Dateien angefordert werden.
Ich habe den simplen Test gemacht und den ApacheBench auf diesem Blog laufen lassen mit den folgenden Einstellungen:
ab -n 500 -kc 10 https://blog.dorianvasco.de/Die Ausgaben zeigten, dass das aktivierte autoptimize Plugin zwar die Dateigrößen reduzierte, die Ladezeiten insgesamt aber sogar verlängerte.
