[Certain older Apple Mac firmware boot faster with the slow stick than the fast one, and it turns out the block size matters. Block size 512 bytes is insanely slow (as in 100KB/s) on the "fast" stick, whereas a block size of even 32k puts it to 20+MB/s. So I think the older firmware must be initially asking for 512 byte blocks, once the kernel takes over the performance is very good.] Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
