Hi,
ich habe 2 Server, einen mit Single-Core und einen mit Dual-Core, einer hat 1 GB RAM, einer 4 GB. Ansonsten relativ ähnlich.
Wenn ich nun folgendes Benchmarkscript laufen lasse, bekomme ich folgende Ergebnisse. Aber die langsameren Ergebnisse auf dem "schneleeren" Server, und das reproduzierbar und immer wieder aufs Neue. Teilweise auch etwas gravierender als untenstehend.
Was haltet Ihr davon?
