Hi!
The prelink friendly binary unfortunately is not the default in FC1, but you can speed up OOo start by: ln -sf soffice2.bin /usr/lib/openoffice/program/soffice.bin as root.
ftp://people.redhat.com/jakub/openoffice.org/ contains openoffice.org-1.1.0-6.1 packages which differ from 1.1.0-6 as present in FC1 in 2 things: a) soffice2.bin is the default, so you don't have to run the above command to speed it up b) it has been compiled with -Os. This seems to save 9MB on allocated library size and e.g. when running oowriter should cut the total size of libraries loaded from around 71MB to ~ 66MB (by ~ 5.25MB). In theory this should speed up OO.o startup time especially when caches are cold (ie. when running oowriter the first time after boot). I've tried to measure some numbers with time(1): cold are after running cat 2.8GB file > /dev/null, hot are 3rd up to 5th invocations of the program, each measurement repeated 3 times. The first numbers are from the default 1.1.0-6 oowriter, second with 1.1.0-6 after ln -sf soffice2.bin /usr/lib/openoffice/program/soffice.bin and third with 1.1.0-6.1 default. Dual PIII, 651MHz. Measuring with time is of course very inaccurate.

hi, would you put these to fedora/linux/core/development/ thanks.

Is it the only difference? Here is the original, I already changed the softlink:
# rpm -q openoffice.org openoffice.org-1.1.0-6 # cd /usr/lib/openoffice/program # ls -l soffice*.bin -rwxr-xr-x 1 root root 446012 nov 3 23:33 soffice1.bin -rwxr-xr-x 1 root root 70904 nov 3 23:33 soffice2.bin -rwxr-xr-x 1 root root 555192 nov 3 23:33 soffice3.bin lrwxrwxrwx 1 root root 12 nov 12 13:50 soffice.bin -> soffice1.bin
The binary size difference is not what you describe, but much larger, oowriter starts up with a huge speed difference!
