Sorry, locate is not even comparable to what Spotlight does. Do a search for mdfind(1) to get an idea of what is does. Recoll is the only thing I found on Linux being actively developed that comes close, but it's definitely not as polished or flexible. I'm primarily running Arch these days, but there are some things that Linux just has no good equivalent for.
But the opportunity cost is never having a true enterprise class file-system. If you look at Linux, OpenSolaris (and it's derivatives), BSD and yes even modern Windows in terms of core technology and performance their file-systems are generations ahead of OSX. What shocks me is that given the BSD lineage of OSX that is hasn't switched to ZFS yet given how Apple prides itself on being the "best of the best" of computi…
What other enterprise-class file system are you talking about? btrfs is still immature, anytime I've strayed from ext, I regret it. And NTFS? I've had lots of more problems w/ that than anything else (admittedly, probably due to poor interactions between Windows and ntfs-3g on Linux).
In any case, since OSX isn't a data-center OS, I don't see what "enterprise-class" storage has to do with it anyway.
