It may well be the case. --enable-gengc activates an incremental
marking mode that uses a generations algorithm together with
information about what pages in memory are actually written to. Right
now both flags are disabled by default, but this is a problem which
deserves careful investigation, specially because the garbage
collector is one of the biggest performance sinks in any Common Lisp
implementation.
