Just did this test (AMD Athlon(tm) 64 X2 Dual Core Processor 4600+).
The times are done by running this command:
$ time oowriter
and then hitting Ctrl-Q as soon as possible. At this point, I used
OpenOffice (yesterday), so it should be cached:
real 0m2.296s
user 0m0.060s
sys 0m0.080s
real 0m2.337s
user 0m0.048s
sys 0m0.092s
real 0m2.360s
user 0m0.024s
sys 0m0.104s
These are fresh times, with the following commands being run to flush and
then load:
# echo 3 > /proc/sys/vm/drop_caches
$ time oowriter
real 0m9.361s
user 0m0.060s
sys 0m0.160s
real 0m10.148s
user 0m0.084s
sys 0m0.144s
real 0m10.090s
user 0m0.072s
sys 0m0.148s
And a quick follow-up without flushing the cache:
real 0m2.571s
user 0m0.036s
sys 0m0.100s
Call it 10 seconds fresh, 2.5 seconds stale.
I can live with it, when I have to read Billy-Box-Dox.
