In the traditional approach we had roughly the following +steps: + +\startitemize[packed] +\startitem the first run information is collected and written to file \stopitem +\startitem after that run the \BIBTEX\ program converts that file to another one \stopitem +\startitem successive runs use that data for references and producing lists \stopitem +\stopitemize + +In the \MKIV\ approach the bibliographic database is loaded in memory each run and +processing also happens each run. On paper this looks less efficient but as \LUA\ is +quite fast, in practice performance is much better. + +Probably most demanding is the treatment of authors as we have to analyze names, +split multiple authors and reassemble firstnames, vons, surnames and juniors. +When we sort by author sorting vectors have to be made which also has a penalty. +However, in practice the user will not notice a performance degradation. We did +some tests with a list of 500.000 authors, sorted them and typeset them as list +(producing some 5400 dense pages in a small font and with small margins). This is +typical one of these cases where using \LUAJITTEX\ saves quite time. On my +machine it took just over 100 seconds to get this done. Unfortunately not all +operating systems performed equally well: 32 bit versions worked fine, but 64 bit +\LINUX\ either crashed (stalled) the machine or ran out of memory rather fast, +while \OSX\ and \WINDOWS\ performed fine. In practice you will never run into this, +unless you produce massive amounts of bibliographic entries. + +\stopchapter + \stopbodymatter \stoptext |
