load(draw) is very slow (takes about 13 seconds)

13 sec is a long time. But I do not expect that this is a bug. I don't
know but I can imagine that sbcl compiles when loading. draw is an
uncompiled share package written in Lisp. I expect draw benefits from
being compiled. If you wish you can explicitely compile the lisp files
in this package and load the binaries. If you do so please note that
draw.lisp itself loads Lisp files. Lines 38/39:
($load "grcommon.lisp")
($load "vtk.lisp")


For the record. This is what I get on a 32-Bit xubuntu (1.6 GHz
DualCore). Note the amount of space that sbcl reclaims when loading
draw.

using Lisp SBCL 1.0.57.0.debian
(%i2) load(draw);
Evaluation took 3.8360 seconds (3.8430 elapsed) using 336.824 MB.

using Lisp Clozure Common Lisp Version 1.8-r15286M  (LinuxX8632)
(%i2) load(draw);
Evaluation took 1.4760 seconds (1.4760 elapsed)

using Lisp CMU Common Lisp Debian build debian/20c-2-1-g957a42a-dirty
(20C Unicode)
(%i2) load(draw);
Evaluation took 0.1700 seconds (0.3400 elapsed) using 11.404 MB.

using Lisp CLISP 2.49 (2010-07-07)
(%i2) load(draw);
Evaluation took 0.1640 seconds (0.1619 elapsed) using 5.021 MB.

using Lisp GNU Common Lisp (GCL) GCL 2.6.7 (a.k.a. GCL)
(%i2) load(draw);
Evaluation took 0.0400 seconds (0.0400 elapsed)
