I looked over files on >about 200 Suns for large files, and the largest single file was under >100MB. Therefore for most applications there isn't a problem. Except, of course, that Sun's MMUs don't work with very large virtual memories, either. I think the Sun-2 had a limit of 16Mb, of course (68010), and the early Sun-3's, at least, had a limit of 64 or 128Mb per process. I could be wrong, of course, but I don't believe they supported all 32 virtual address bits. -- Sean Eric Fagan | "Time has little to do with infinity and jelly donuts." seanf@sco.COM | -- Thomas Magnum (Tom Selleck), _Magnum, P.I._ (408) 458-1422 | Any opinions expressed are my own, not my employers'.
