	If you happen to be using Solaris, either
	Ss 7 or 8, add "logging" to the options field
	in yout vfstab and remount the disk.

	The Solaris metatdata-loggiong option helps
	applications whih do lots of directory 
	foolishness: it indirectly helps searches
	by freeing up pessimaly-retained cache pages.

	Changing the subject slightly, I didn't realize
	thre was a samba-side cache, although I know it was
	discussed.  Perhaps an option of the form
		# Tell samba how many entries to expect
		largest dir = 2049  
	might be used to hint at a cache size???
