Asterisk's AGI interface performance issues can be a limiting factor in high performance installations. This post details how we used agi+inetd for a 4x improvement in calls per second (cps) with minimal change in our agi code

Diskless desktops give better manageability and central control. Read this link for some reasons to use diskless servers, arguments equally valid for diskless desktops.
1. Introduction
However diskless desktops often suffer from performance issues, and if they number more than about 20, they are also prone to network congestion and NFS server load.
This tutorial will help you setup high performance diskless desktops employing NFS-caching, a feature of kernel 2.6.30 onwards. FS-cache allows NFS resident files to be cached locally on a USB stick or hard disk transparently to the user. For more info on fs caching visit this link
