I was wondering: is there a way to achieve something similar just using the I/O cache?
My laptop is meant to run Vista and thus comes with 2GB of RAM, of which Linux (or even XP!)
does not use that much; it would be nice to tell the system to not flush some parts of the FS
to disk and keep them in RAM for a very long time, without having to set-up a RAM disk and
then committing it to disk on shut down...
More concretely: my source code is like so:
all the file_test_dir's are big and contain big useless short-lived data. what is below is
important code. I'd love to be able to say: *test_dir does not be need be sync'd to disk at
all, or very rarely.
Ok, just writing it lets me think that's it's not trivial unless I do create a RAM disk for
my test data... oh well.
Or maybe unionfs can help?
