Timo,

I swear I read somewhere that you had implemented something like this,
but I can't find it. Is it still necessary to disable the attribute
cache to put indexes in NFS?

If so, do you have any idea how much of a performance impact that is vs.
clearing the attribute cache as needed? Any idea what it would cost to
have you code this feature?

Thanks,
Richard
