3449.0. "FACC II ?????????" by GIDDAY::MORAN (I'm not bad, I'm just drawn that way!) Wed Feb 07 1990 00:47

    I have a program running on my non-hard drive amiga system called FACC.
    It's just a disk cacheing system that speeds up the floppy drive read
    process.  I saw an ad in a amiga magazine the other day seling FACC II,
    but they did'nt give any desciption as to what the difference is.
     
    I was wondering if any of my amiga friends out there have heard of this
    prouct and if so could you tell me what the advantage of having this
    new version is.
    
    Thanks Shaun.

	Re: .0 Facc II requires slightly less memory to run because its user interface was made into a separate program Facction. You run Facc and it does the disk caching. If you want to see how well Facc is doing, you run Facction, and it opens the window with all the gadgets and then talks to Facc via the Amiga interprocess message passing. The biggest benefit is you don't have to have that little Facc control window floating around you screen :-). At one time, ASDG did free (or real cheap) upgrades of Facc to Facc II. You had to send them your original Facc disk, and they sent it back with Facc II copied on top of it. I don't know what the current deal is, as I upgraded two years or so ago!

	Forgive me if these are dumb questions, but is it worth it to use FACC II instead of Addbuffers? If so, can FACC II be used on harddisks also?

	Re: .2 Facc and Facc II are better than addbuffers because it is more efficient in checking to see if a buffer contains the disk block you are interested in. I remember some claim of "Facc can check 256 buffers in the time that AmigaDOS checks 30". Facc and Facc II allow you to decrease the number of buffers that you are using, if you run tight on memory between reboots. There is no way to take back AddBuffer buffers. Addbuffer buffers for floppies use chip ram. Facc and Facc II buffers use fast ram, if you have it. So, you don't have to choose between fast floppy access or being able to pain high res pictures with Deluxe Paint. Facc II, but not Facc, knows about the structure of the filesystem for floppies. It tries to retain directory and file lookup blocks in its buffers because it knows they are frequently used. I heard a rumor, that AmigaDOS managed floppy buffers had a bug that caused the "must recently used buffer" to be chosen for replacement.
