Anyone remember the old days when we thought 64k RAM and a 5MB hard drive was a fast machine?

Yes - I am not saying my entire farm has that much ram. You can get away with much, much less, but I have servers that go that high.

    Did I read that right you have 768GB of RAM?

        This is kinda new to me - Just so I am clear - unganged
        systems would perform better if I have say - a caching system
        with limited threads each pined to a specific core (we do this
        for processor cache anyway) while ganged systems would perform
        better it I was spinning up a new thread for each request and
        had a large amount (say 768GB) of ram running something like
        PostgreSQL where threads are being fired up and down many
        thousands of times a second but the data they seek is mostly
        in main memory.

            And by usually will not I mean I have never sen it do so,
            even in the days of ghetto ram thieving by graphics chip-sets.

                    Why less than 3/4 of it?


                Perhaps the bios has allocated a chunk of it to
                onboard video?
