RFT: openoffice.org tweaks to speed up startup

[Jakub Jelinek]

Hi!

I've done some tweaks to OO.o to make it more prelink-friendly
(and thus to start up faster).
ftp://people.redhat.com/jakub/openoffice.org/
contains openoffice.org-1.1.0-3.1 package, with 2 differences
against 1.1.0-3 in rawhide:

1) there are 3 variants of the /usr/lib/openoffice/program/soffice.bin
   binary (the actual OOo program), soffice.bin is a symlink to one of
   them:
   soffice1.bin should be the same as soffice.bin in 1.1.0-3
   soffice2.bin instead indirectly links against another > 40 libraries
		which are ALWAYS dlopened when soffice starts
   soffice3.bin is like soffice2.bin, but unlike soffice2.bin, it has
		all DT_NEEDED tags directly in the binary, while
		soffice2.bin is just crt files and all the binary's
		code plus most of the DT_NEEDED tags moved to
		new shared library
2) IMHO there are too many wrapper scripts, so there is a change
   in ooffice script to avoid /usr/lib/openoffice/program/soffice
   script which does things like check for Solaris installed patches
   and whatever else and instead just run the pagein and soffice.bin
   binaries directly with right env variables and options.
   If you have problems wit this change, just do:
   perl -pi -e 's/# exec/exec/' /usr/bin/ooffice
   and you'll get previous behavior

I'd like if you could test all 3 sofficeN.bin binaries on a prelinked system,
ie.:
1) as root: install the above package
2) as root: /etc/cron.daily/prelink
3) as normal user:
for N in 1 2 3; do
  ln -sf soffice$N.bin /usr/lib/openoffice/program/soffice.bin
  run OOo a couple of times, test. Measure startup time.
  Run
  LD_DEBUG=statistics /usr/lib/openoffice/program/soffice.bin private:factory/swriter
  a couple of times
done

and tell me how do you feel it starts fast and average output of
LD_DEBUG=statistics (just the first 10 lines is enough) in each of the
3 cases.

Thanks.

	Jakub
