Hi David,

1) Temporarily try with ipappend 3 in pxelinux.cfg/default (google for instructions). This will eliminate the DHCP delay and let you compare the boot times more easily.

2) If your router has 4 LAN ports, use it as your "main switch", i.e. connect all the other switches directly to the router, don't chain them.

3) What are the client specs? Better CPUs boot faster...

4) Bootchart can measure boot time delays.
