I don't see why mmap is any more out of reach than O_DIRECT; it's not all that much harder to implement, and mmap (and madvise!) is more widely available. But if using two caches is only costing us 1% in performance, there's not really much point.... cjs -- Curt Sampson <[EMAIL PROTECTED]> +81 90 7737 2974 http://www.NetBSD.org Make up enjoying your city life...produced by BIC CAMERA ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
