I've found that the amount of memory available to the JVM makes a BIG 
difference to build performance.

Upping our build machine from 128M to 256M accelerated our builds from 
45min to 15min.

Note that the amount of memory available to the JVM isn't necessarily the 
same as physical memory. Have a look at the options available to java.

For example, on our build machine we use -Xmx200M (set maximum heap to 200Mb).

Hope this helps,
