Merhaba arkadaşlar,
WordPress sitelerinizin bulunduğu sunucunuzunun performansını uçurmak Varnish kurdunuz. Yetmedi birde W3 Total Cache eklentisini kurdunuz.
Artık web siteleriniz müthiş hızlı. İşin güzel yanı sunucunuzun load durumu veya kaynak tüketimi neredeyse yok. Herşey güzel. Birde Varnish default.vcl dosyanızı WordPress’inizle müthiş bir uyumla çalışacak hale getirmek ister misiniz? Matthew Jackowski abimiz çok güzel bir VCL dosyası hazırlamış. Sizinde kullanmanızı öneririm, oldukça başarılı. Buyrun default.vcl kodumuz:
