Hallo,
welche Möglichkeit habe ich, um den Socket- und RAM-Bedarf zu senken, und was sind die Ursachen?
Das Paket ist ein älterer vserver bei vanager, scheinbar haben sie den Festplattenplatz noch nicht auf aktuelles Paketniveau angehoben:
Aktuell:
Webspace 10 GB
Traffic pro Monat 300 GB
Arbeitsspeicher (RAM) 256 MB
Garantierte CPU-Leistung 100 %
VPSadmin info:
Speicherplatz enthalten 1.536 MB
Speicherplatz belegt 931 MB ( 61 % )
Mir als Linux-Laie fällt auf, dass es anscheinend keinen Swap gibt. Weiterhin gibt es eine handvoll Child-Prozesse, die ich bei meiner minimalen Serverauslastung wahrscheinlich genausogut reduzieren könnte.
Leider weiß ich nicht genau, welche Schlüssel in den einzelnen Konfigurationen diese Zahl festlegen, und wie die Zusammenhänge/Auswirkungen sind.
Aus meinen bisherigen Recherchen habe ich folgende Info-Befehle zusammengetragen und ausgeführt, in der Hoffnung, dass Euch das mehr sagt, als mir:

Ich liefere gerne mehr Infos. Ich bedanke mich.
welche Möglichkeit habe ich, um den Socket- und RAM-Bedarf zu senken, und was sind die Ursachen?
Das Paket ist ein älterer vserver bei vanager, scheinbar haben sie den Festplattenplatz noch nicht auf aktuelles Paketniveau angehoben:
Aktuell:
Webspace 10 GB
Traffic pro Monat 300 GB
Arbeitsspeicher (RAM) 256 MB
Garantierte CPU-Leistung 100 %
VPSadmin info:
Speicherplatz enthalten 1.536 MB
Speicherplatz belegt 931 MB ( 61 % )
Mir als Linux-Laie fällt auf, dass es anscheinend keinen Swap gibt. Weiterhin gibt es eine handvoll Child-Prozesse, die ich bei meiner minimalen Serverauslastung wahrscheinlich genausogut reduzieren könnte.
Leider weiß ich nicht genau, welche Schlüssel in den einzelnen Konfigurationen diese Zahl festlegen, und wie die Zusammenhänge/Auswirkungen sind.
Aus meinen bisherigen Recherchen habe ich folgende Info-Befehle zusammengetragen und ausgeführt, in der Hoffnung, dass Euch das mehr sagt, als mir:
