Package: sbcl Version: 1:0.9.6.0-12 Severity: normal Hi, Peter. in install-clc.lisp, you call save-lisp-and-die with :purify t. This is a performance pessimization on x86 and x86-64 (since Juho Snellman's work on page table iteration in the generational garbage collector). If you took out the explicit :purify keyword argument, it should Do The Right Thing on all platforms.
