That's reducible to the standard debate of static vs dynamic linking in any language, surely? The only "impact" on performance presumably is the re-writing of the symbol tables which flexlink/dlopen does as the .cmxs file is loaded but that must be negligible. However, isn't ocamlopt able to do some cross-module optimisation (which is why .cmx files are usually shipped as well as .cmxa) - this presumably isn't possible when linking dynamically... Short-term, native dynlink doesn't work on all platforms (AFAIK?) so .cmxa is not dead, whatever your linking preference. David _______________________________________________ Caml-list mailing list.
