I want to know if i am doing things correctly and is XML::Compile really slow?
You appear to be doing things correctly ... if all the modules do what you want with the code you included
And yes, XML::Compile is probably that slow :) OTOH it does more than the other modules (and does it in perl code), so the slowness isn't unexpected

My advice (that I'm advising you with) is to try XML::Rules its XML::Simple on steriods :)
Also, profile your code (nytprof) to identify other bottlenecks :)
Also try XML::Hash::XS -- its libxml2+xs -- should be as fast as you can possibly get
