5.4 has a significantly more power which makes the build process more 
complex and thus slower. However we've never actually profiled the build 
process to attempt to improve it's performance or reduce memory. We 
won't get around to improving those for 5.4, but we will address it as 
some point in the future, I know that Mario is itching to get parallel 
rule building :) As always code contributions are welcome :)
