title: how to use nfs with magento webserver in a cluster environment
body: <p>i'm having a little hard time makeing a magento EE installation faster. The environmen is built on CloudStack with lodabalance, 2 x nginx webserver with php onboard, 1 x vm with a nfs share exported, 2 x percona cluster, 1 x redis / memcache</p>
  
  <p>now, i have placed the magento folder directly on the nfs exported share, i mean the complete magento folder and webservers have the share mounted and serving all the content from that folder.</p>
  
  <p>websites are slow, not very slow but slow. my question is:</p>
  
  <p>in a clustered environment with many webservers and a nfs share, is technically correct to place all the magento folder on it, or it's better to export only the /media folder on the nfs and the somehow (cron + rsync?) sync contents between nodes?</p>
  
  <p>thank you</p>
