I have an initial cluster consisting of several desk top computers

 - Pentium 4 3.80GHz -
 - 2-4G of memory -
 - 1 Gigabit NIC -
 - 1 Disk, Serial ATA/150 7,200 RPM -

These machines are connected using an old 10/100 switch.

Tuning Hadoop is not increasing performance.

What should I upgrade?

 - memory? -
 - add NIC's? -
 - Add disks? -
 - Better switch? -
