[CentOS] loading a program in memory for faster startup

After searching for a way to load a program in memory for fast start time I found preload.sourceforge.net

I then kept looking and found CentOS 5 has readahead_early and readahead_later.

I have (2) questions.

1) the /etc/readahead.d/default.later file has firefox 1.5 preloads mentioned. That seems REALLY old. shouldnt that be updated?

2) can I just add the path to oowriter to /etc/readahead.d/default.later and oowriter will be ready all the time to just run from memory and wont have to load from disk?

Is there a /etc/readahead.d/local type file to add oowriter to instead of default.later?

Thanks,

Jerry
