Wow - that's a blast from the past. Intel did some work to enable tcmalloc to be used - one of those micro-optimisations that people hope will make things faster and often do - but only linearly. > Currently it defaults to "internal" perhaps this should be changed to > default to "system".

Right - so, we should do some performance tests of characteristic documents with the internal vs. system allocator. AFAIR the system allocator is rather good on Linux, and terrible on Windows ;-) so possibly we should have a platform-dependent default. As for the tcmalloc and abcmalloc options I'd be inclined to strip them out as cruft we can live without these days. Is that reasonable ? I'd just do 3x timing runs for startup / document load / exit for some reasonably large .doc, .ppt, and .xls [ chosen for their faster, non-XML impls. by the way ]. if you use: export RTL_LOGFILE=/tmp/startup.nopid and remove that before running, you -should- get some nice timestamps in it that can be used to test. It'd be wonderful to have some new research in that area to build better decisions on.
