I have noticed that bigfloat computations are quite slow with Clozure.
E.g.:
on XP:
Maxima 5.20.0 http://maxima.sourceforge.net
using Lisp Clozure Common Lisp Version 1.4-r13122 (WindowsX8632)
(%i1) bfloat(%pi), fpprec:10000$
(%i2) time(%o1);
(%o2) [1.222]
(%i3) bfloat(%pi), fpprec:100000$
(%i4) time(%o3);
(%o4) [124.569]
on XP:
Maxima 5.15.0 http://maxima.sourceforge.net
Using Lisp GNU Common Lisp (GCL) GCL 2.6.8 (aka GCL)
(%i1) bfloat(%pi), fpprec:10000$
(%i2) time(%o1);
(%o2) [0.09]
(%i3) bfloat(%pi), fpprec:100000$
(%i4) time(%o3);
(%o4) [3.51]
on Ubuntu:
Maxima 5.19.1 http://maxima.sourceforge.net
Using Lisp CLISP 2.44.1 (2008-02-23)
(%i1) bfloat(%pi), fpprec:10000$
(%i2) time(%o1);
(%o2) [0.108007]
(%i3) bfloat(%pi), fpprec:100000$
(%i4) time(%o3);
(%o4) [4.844303]
