[info-mcl] Performance differences between 5.1 and 5.2.1

I noticed (and measured) an important performance difference between
my application running on RMCL 5.1 and the same application running on
Only loading all the application code, from a fresh RMCL delivery, it
takes on 5.2.1 almost twice as much as in 5.1. Then, every
functionality is slower on 5.2.1 and for some specific application
tasks I could even measure a difference of a factor 4.
I was wondering if someone else is having such performance problems
In both cases I am using a 1 GB dump, which, btw, on version 5.2.1
shows such warning on the listener:
Welcome to Macintosh Common Lisp Version 5.2.1!
; Warning: Requested 1073741824 bytes of heap. Max is 1073000000 bytes.
; While executing: CCL::CHECK-CARBONLIB-VERSION
Is there a connection?
