For normal guile I used 1.8.1, default gentoo build. (-O2) For GC guile, I built from your tree. (also -O2) Snd is snd-ls V0.9.7.12. My machine is an XP2800, single processor. Running the benchmark program directly in guile gives no difference. Both= =20 spent about 50 seconds running the test. Inside snd is another matter: [1] [2] [3] Guile gc 96mb 176mb 54s. Boehm gc 99mb 107mb 118s. [1] Memory before running test reported by top. [2] Memory after running test reported by top [3] Time to run test in seconds. All tests performed twice to ensure nothing special happened in one of=20 them. The numbers here are from last test, and are about the same as=20 from the run. --8323328-1643755891-1180973461=:9033 Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Guile-devel mailing list Guile-devel@gnu.org http://lists.gnu.org/mailman/listinfo/guile-devel --8323328-1643755891-1180973461=:9033--
