I ordered the JiffyDOS ROM and installed it a couple weeks ago. Before and after installing, I did some tests with my 1581, and I'm wondering what other JiffyDOS users think about this. All testing was done using a C128 in C128 mode. So here it is: Without JiffyDOS, it took 8.5 seconds to load a 191 block file from my 1581. With JiffyDOS it also takes 8.5 seconds to load the same 191 block file. Booting ACE w/o JD took 21 seconds. Booting ACE with JD takes 21 seconds. Not a half a second difference. Booting Desterm w/o JD took 24.4 seconds. It was a bit hard to measure here because Desterm starts by playing music, but with JD I think it was a half or a full second faster to boot. ~ 23.5 Booting Dialogue 128 (from the time I type BOOT U9) w/o JD took 29.5 seconds. Booting Dialogue with JD now takes exactly 29.5 seconds. No difference. Time it takes to download 2 .D64 files to an empty 3 1/2" disk when using Dialogue and a 14.4 modem (Screen Output set to None): W/o JD it took 08:25 minutes. With JD it took 08:18 minutes. That is a total of 7 seconds faster. Or 1.4% speed increase. OK. One thing is peculiar about the Dialogue boot. The loading time comparisons in the Dialogue manual indicate a 4 second speed increase with JD. So how can that be? Hmmm... Obviously all of my testing falls far short of the speed comparisons in the JD manual. I expected that I would only get a slight improvement when using my C128 (as opposed to C64 mode) with the 1581. But none! In the JD manual in gives numbers for Saving files indicating an 85% increase in speed. And as I said, I only got 1.4% with the .D64 files. So I am at a loss. :( - Adam Vardy ========================================================================= Date: Tue, 4 Jun 1996 17:16:36 -0700 Reply-To: COMMODORE COMPUTERS DISCUSSION Sender: COMMODORE COMPUTERS DISCUSSION From: Sean Roe Subject: Re: 1581 JiffyDOS tests At 04:00 PM 6/4/96 -0230, you wrote: > I posted a message to this mailing list around a month ago asking >about the performance of JiffyDOS for the 1581.

Yes, I do have JiffyDOS in both my C128 and my 1581. It works great with my 1571. > both to make it scream! I have a 1581 w JD and there is a huge difference > between JD and regular. There is a marked difference in 64 mode. But 128 mode appears to be another story.

The reason I ask, is in the manual it states somewhere that when you use disks that are formatted with JiffyDos, that you will see a difference in load/save/read times. Try your tests again with disks formatted using JiffyDOS (IE, with JD active). This works in reverse too. If you give someone a disk formatted with JiffyDOS and they don't have JD, their disk access times will actually be slower than if it were a standard CBM DOS formated disk. Actually, what the manual talks about is differences in the interleave. This applies to saving files on the disk, rather than formatting. However, I don't think it applies to the 1581 at all: On the 1541 and 1571 drives, the drive reads one sector at a time, and has some pause time in between sector reads. Since the disk still spins during this time, if you put sectors in sequential order, the disk would have to make a full revolution between reads to get back to the next sector. To speed things up, you try to set the interleave, or number of sectors to skip before writing the next sector of a file, to a value that allows the disk to spin to just about the right spot before it's ready to write the next sector. However, the stock 1581 comes with enough RAM to simply read an entire track in one read, thus eliminating the need for an interleave. When you do a sector read on the 1581, it reads in a full track, and then gets the individual sectors from RAM. I'd imagine that the JD 1581 ROM does the same thing, since it's much faster than going back to the disk for each one. Aaron -------------------------------------------------------- Aaron J.

Anyways, if you are using a 9600 baud modem on a 128, you can do it with just a RS-232 interface. You don't need the Swiftlink (from what I understand, the 128 will go 9600 baud without any other help) (I know that Rod Gasson or Gaylene might be able to help out here). Downloading to a 1581 (the fastest Commodore drive) should be fairly close to 9600 baud. From what I've seen, this should be correct.

Christopher, There is any easy fix for that. What you can do, is hook two modems up together by using a phone line, and then having the computers call eath other. A friend of mine does that with his Amiga and 128. He says that when he is d/l'ing files, it is fast as all get out. He is not sure of the speed, but he figures it is well over 9600 baud.....and that is using 2-2400 baud modems. He just sets his speed at 19,200 and goes at it. I'll check out his commands for you if you like.
