Well, I thought the preferences were identified as the performance  
You may want to test using a File System PM and see if that helps  
boost performance
I can see where the pages being read out of the database could be  
slower than pulling them off the file system
So you would need a similar approach as outlined in the last email to  
preload pages
I think you could simply use the PageManager API to make calls to  
load the page, and it will load the cache
Of course you will need to adjust the cache eviction as well
