Sto eseguendo centos 6.3 all'interno di VirtualBox 4.2.1 sul mio computer OSX 10.8.2 e ho riscontrato un problema di latenza che non comprendo. Fondamentalmente, ogni richiesta http verso qualsiasi luogo ha un ritardo aggiuntivo di 5000 ms. Ping non ha alcun ritardo aggiuntivo.CentOS VirtualBox 5 secondi di latenza su richieste http
