Yes, but for some kinds of software, like programs with custom gui's,=20 sound processing programs, interactive graphical programs, interactivety=20 is exclusively more important than those two. I consider the freeze that=20 the guile's built-in gc cause to be its biggest problem. In fact, I don't think execution time is an important factor here at all.= =20 Don't get me wrong, of course execution time is important in general, but= =20 a change in execution time of a gc benchmark program within the factor of= =20 two sounds like an insignificant difference compared to what is gained in= =20 interactivity. > For instance, with the default settings, Guile + Boehm GC is slightly=20 > faster than Guile when running `gcbench.scm', but it might consume more= =20 > memory.

I might even release a special version of SND=20 with guile + the Boehm GC included to the public in the near future,=20 because of the huge advantages it has. This might generate a lot of=20 feedback. And if no one reports back, then its a good sign that it works=20 well. --8323328-17981105-1180958912=: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 --8323328-17981105-1180958912=:9033--
