For Solaris at least, you can make these updates asynchronous.
There is a program floating around called "fastfs" that will change a
file system from "slow" to "fast" and back again.
Making a file system "fast" makes a HUGE difference to restores or
mass deletes.
There is a risk associated with it: systems or power failure when the
file system is "fast" recent changes will be lost.
