The lofi-mounted vs. copied to disk numbers above would seem to indicate no substantial impact there; it's not actually on DVD media, which is the real read latency killer. I'll note that the AI times Peter quotes are similar to those found in the internal testing of x86 virtual box instances done over http. The corresponding Jumpstart numbers are very different, but that may be a virtual box artifact. Dave
