My "not-so-meaningful benchmarks" (running a > loop[*]) reproductively show that "GBGC" is noticeably slower than "real > Guile" (1.5 to 2 times slower). the following options turn on generational GC GC_enable_incremental (); GC_time_limit = GC_TIME_UNLIMITED; with this, I get (very) slight performance improvement. For the 32mb tree test, BGC is 40% slower, for the 128mb tree, it's 31% (disregard the previous figure of 23 %, it was an error in calculation, it should have been 33 %) -- Han-Wen Nienhuys - hanwen@xs4all.nl - http://www.xs4all.nl/~hanwen _______________________________________________ Guile-devel mailing list Guile-devel@gnu.org http://lists.gnu.org/mailman/listinfo/guile-devel
