So ... this looks very much like a typical victim-of-the-second-start problem.
Indeed - I find it very hard to believe that this setting:
## Type: string
## Default: 5
# Limit the size of the memory that a single process may lock in
# physical memory (thus preventing it to be swapped out).
# Hard limit: Can not be increased by non-root.
# This value corresponds to ulimit -Hl
# Parameter is in percent of physical memory (unless you prefix
# it by @, in which case it means kilobytes), 0 means no adjustment.
is at all significant - particularly since OO.o will not try to lock
anything in memory anyway - you can verify this by stracing - and looking for
'mlock' syscalls [ there are none ].
So - unless there is some mechanism by which things should be faster it
looks to me like an abberation caused by noise in measurement.
Furthermore - if OO.o crashes - we want a stack-trace, not a rumor of one:
we can fix real crashes.
If you -really- want to measure such things; you need to have a repeatable
setup: you need to boot your machine from cold, and execute soffice as part of
the startup; you then need to repeat that several (at least 4) times both
before and after your suggested change.
There is some built-in logging in OO.o to help you with that.
export RTL_LOGFILE=/tmp/startup.nopid ; rm -f $RTL_LOGFILE ; export
OOO_EXIT_POST_STARTUP=1 ; oowriter
that should give you a /tmp/startup.nopid file with timestamps in it for
Bear in mind we need a statistically significant number of these, and low
jitter to make any meaningful comparison.
Of course, there is an outside chance that this setting has some amazing
effect on the Linux VM - if so, we need to carefully isolate that, and make
sure that this works without endangering the system by tweaking random settings
unrelated to OO.o :-) [ that is useful work to do ]
Thanks for caring about OO.o startup time though ! :-)
