I have more than a year of experience in using compiled or unexeced boot-9.scm on the following platforms: Linux, Solaris and HP-UX. 1) Compiling boot-9.scm: you are roughly 4x faster at start-up time, and when you run your other files (even interpreted), you have in most cases a noticeable speed boost, sometimes 2x faster. When compiling with hobbit, you build dynamically linkable libraries by default, but linking statically is also possible for platforms without dyncall capabilities. 2) Unexecing boot-9.scm: no noticeable startup-time at all !! But the speed after that is not modified of course. In guile-hobbit-1.3, there is an extension of unexec for the above 3 platforms. 3) Compiling + unexecing.... This works only when boot-9.scm is compiled statically. I have no first hand experience with this, as the start-up time of 1) is sufficient for me. So the least common denominator for all platforms is to compile statically boot-9.scm and link the resulting library to the core interpreter. Nevertheless, current boot-9.scm MUST be modified (eliminating all non-R4RS and guile's specific syntax constructions) to be compiled by hobbit. In addition, the debugger will sometimes output strange things when refering to boot-9.scm definitions. There is also the problem of the discrepancies between the changing guile run-time interface and what hobbit expects. So the current guile-hobbit-1.3 does not work with recent snapshots if you do not apply some patches. (I hope to catch up with the release of guile-1.3.) -- B. Urban
