I vaguely recall something about your boot partition having to be FFS formatted - was this just for the pre-release or is it still the case?

No, also SFS can be used (it has been so for a looong while now). SFS2 and JFXS can not, though, because the SLB does not support them yet.

Good idea and good move, but, without wanting to rain on your parade, I only take it as a promising sign (here wishful-thinking)

Edit: sorry, just read the official news - well done to all!

4. Use Mediatoolbox to change to SFS - something I should be aware of here?

Ensure blocksize is set to 512 (mandatory).
Also, you may want to raise buffers to 1000.

Hmm ? I'll try this evening on my own A1. Which FS are you using ?

SFS, but I think it is unlikely that it has something to do with it because, as said, ASL requesters treat links correctly - in other words, I think it is just a problem with the TextMode.

This sounds strange (and serious): RAM does not get freed after usage of swap memory.
Test:
1. copy to RAM Disk more stuff than than it can hold (swapping kicks in correctly);
2. delete everything from RAM Disk;
3. free RAM is reported to be 0 (or little more) even after an "avail FLUSH".

(Problem originally reported by Menthos here.)

Edit: it does not seem to be a bug, but just a smarter way of allocating memory - here is a simple test that I did:
1. after a reboot, I opened a shell and executed avail FLUSH, which returned 185.196.544 bytes free;
2. I copied a ~28 Mb file to RAM disk;
3. I executed avail FLUSH, which returned 158.597.120 bytes free;
4. I deleted the file from RAM;
5. I executed avail FLUSH, which returned again 158.597.120 bytes free;
6. I copied the file again;
7. I executed avail FLUSH, which returned again 158.597.120 bytes free.

In a nutshell, the memory gets re-used and is re-/de-allocated only when strictly needed.

That's not a problem of AmiDock.. every (app)docky is free in its decision if it reacts on single- or doubleclicks. AmiDock just informs the docky about what happened, but the Docky itself is responsible to react to the action.

So if one docky opens a window on single click and another docky only after doubleclick, it was the decision of the dockycoder to do it that way and not AmiDocks.

I think that there could be problem instead: a couple (or few more) times it happened to me that I clicked on the icon of an application (not a docky) and it did not start.

More not so serious issues:
- softlinks to drawers are displayed just like drawers in WB TextMode (but are correctly handled in ASL requesters);
- makelink does not trigger updating of WB listers;
- Amidock background is not 100% transparent when Icon area is set to Transparent or Transparency is set to 100% (behaviour differs);
- menus transparency is still fake (not a bug, though);
- E-UAE crashes when stack is not big enough (wasn't automatic stack enlargement implemented?)

Er... SFS is loaded with the kickstart. If one file in Kickstart cannot be loaded, then you have a much bigger problem than your SFS partitions.

There are no obscure reasons whatsoever you would be able to boot at all but SFS would not load.

Let's assume that it's just a problem with just the SYS:Kickstart/SmartFileSystem file: wouldn't the FS stored in the RDB make for a good fallback FS?
Another question: if the HD were attached to a Classic Amiga without AOS 4.x, wouldn't the FS enable the mounting of the partition (think of data recovery)?
(Yeah, I know, these are definitely extreme cases...)

AmigaOS 4.1 benchmark

Posted on: 2008/9/15 20:46 #591

Out of curiosity, I performed a few tests to see how AOS 4.1 compares to AOS 4.0 (on the same machine with the same settings, of course).
The conclusion is that AOS 4.1 is (slightly) slower almost always, although an important aspect like system memory to video memory transfers seem to have improved noticeably.
Note that these tests do not prove AOS 4.1 is slower than AOS 4.0 in absolute: they cover only some aspects in a idle enviroment, so it could well be that the overall performance during normal usage is better (f.ex. thanks to the composition engine moving some of the load from the CPU to the GPU). Moreover, let's not forget that AOS 4.1 has some added functionality that may come at a cost

These are not really problems, but here they come anyway...

- interpretation/handling of BUFSIZE tooltype of AsyncWB seem to have changed: I used to have it set to 1 Mb, but that now makes file copying crawl (maybe the magnitude has changed so that it caused VM to kick in?) - I eventually found out that 32768 is better than leaving it unspecified and than 65536;

- a 68k version of the latest SmartFilesystem (1.282) is not included, which means that the installed SmartFilesystem cannot be updated (the last public one is version 1.279);

- (as mentioned in here on AW.net) ASL now requires a double-click to enter directories.

The thing is I had been sticking with FFS, just in case my A1 blew up and I had to transfer the hard drive over to my A1200.

SFS also comes as M68k binaries that can be installed in the RDB*, thus - I guess - access to SFS partitions should be possible also on AOS 3.x (f.ex., see this post by Rogue). Since it is such a delicate issue, it would be nice if anybody could give a confirmation.

*Indeed, as Joerg explained, those are the only binaries allowed in the RDB.
