I've heard from our close-to-sun sources that caching of home
directories (or any directory with significant amount of writing going
on) is ill-advised. And you will suffer performance loss and possible
file corruption if something hiccoughs. even though write-through and
write-around options are there, you really don't gain anything in
performance if you are doing a lot of writes (which you are likely to
do in your home directory). So, sun advises against that.. /usr and
all software though is great! (what I do)
