OpenSAML user discussion

Hi, we are running into some memory problems with what appears to be the 
opensaml bootstrap process.  I have outlined a few questions below:
1) Are there any specs on the memory footprint of opensaml using the default 
bootstrap configurations?
2) We have 2 web apps in the same JVM that use features of opensaml.  The 
bootstrap loading kicks in when each web app is initialized.  How bad of a 
thing is thing?  Does running the bootstrap over again just compound all the 
memory requirements?
3) Can I modify the configuration so that only what I really need is loaded?  
We are only generating an SAML 1.1 post request at this point. Or does that 
require you to write your own loading process?

thank you in advance, Kurt
