title: Slowness while using NFS shares on kubernetes
body: <p>I have a K8s-Cluster running which had some Pods/Statefulsets running PostgreSQL.</p>
  <p>As PersistenVolumes I only have a NFS-Shares. Now the performance of the PostgreSQL is getting slower.</p>
  <p>Can it be related to the fact I'm using NFS-Shares?</p>
  <p>What should I use instead?</p>
