General-purpose registers, yeah, sure. This might create performance problems, but i386 is as capable to get the processing done as amd64. Could you elaborate on the MMU bit? I'm not aware of huge changes that cannot be emulated by PAE, too. I don't defend i386, but your overly brief formulation of issues look like FUD to me. Your references (in the blog post) also didn't back that up. You might run into addressing trouble with virtual memory management, due to the size of the caches ZFS wants. But then state this instead of refering to unrelated issues at hand. Thanks Philipp Kern -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
