@ Hyperion or someone in the know.

Am I right in assuming OS4 Beta/developer is currently using the old memory allocation system and not the discussed "SLAB" system beeing implemented as a major cnage for OS4? If SLAB structuring has been implemented I would really like some info on just how much of a performance increase it has made using this new slab system if any etc...

anyone got any info on how it all performs in relation to the old system??

just out of plain curiosity of course ;)

No, the new system is in place since roughly half a year (IIRC, it was already in beta at the time update 4 came out, but not included in the latter to give it more time to mature).

The simple test of 100000 allocations followed by appropriate deallocations was between two and three times faster, but this is not a good test since it's far away from any real test. In reality, it's much better than that.

Memory pool performance went up by factor 10 to 20.

@EntilZha

The speed increases are from isolated programs testing the memory system? Or?

How about general speed up of OS and applications running on the system?
Will we notice any speed up or only less fragmentation IRL?

How can a fast OS become faster ?

Nearly all programs are noticeably faster. No quantative comparisons, but the whole system is more responsive.

are you now already planning and building update #5? any idea what will be part of it or especially what will not be part of it?
for example the memory system?

thanks and
byebye...

Yes.

That depends on the application. You can't really say "the system is faster" because it depends on whether there's memory allocation going on or not... in an idle system, the number of memory allocations is pretty low (although even when you do nothing, there is memory allocation and deallocation going on). When you launch, say AmiPDF with a very complex PDF, you are likely to see a difference since loading the PDF means a significant amount of memory allocations.

There's, to the best of my knowledge, no update 5 planned.

I can't give you any raw numbers but I do know some operations are insanely faster such as linking a large C++ program. From minutes to seconds. OS4 is at the stage where optimization is something the devs can look into and they are doing a great job so far.

Could I sign up as a beta tester?
Pretty please.

This sounds good. The only problem with this news is that I have to wait until I get access to these optimizations.

Bad example, if you load an old kernel you'll probably notice that it's still fast now
No idea if the current kernel memory systems have reached the speed of the new newlib.library memory system already, that actually could be the case, but it's not used anymore in newlib anyway ... You'd have to install an old newlib.library which still used the AmigaOS memory pools instead of an own memory system and the current kernel to test that.

@ikir

If you read a bit between the lines, maybe it's not so bad...

If you take those two together, it could mean that a final release is being considered instead of update 5; if Adam and/or Troika are under some sort of NDA so that they can show hardware to Hyperion but not to anyone else, it is possible that this time we really are in the home stretch but just don't know it.

Then again, the Friedens have said in the past we shouldn't read things into what they write, so maybe it's all just a bunch of wishful thinking

@CodeSmith

11 days ago in irc main channel, mention was made of a "possible" service pack
to be made available to the general public. That is not the same as a full update.
afaik, no decision has been posted since then, concerning that possibility.

You mean a Boing Bag? Really? It was so cute and aptly named back in those days of 3.x...
Service Pack sounds so, ehm, windowish. OTOH it might keep Helgis from going PC + Vista now that we get a SP treat!

1st, it for Hyperion alone to answer as to whether this is more than just a
-possibility-.
2nd, lets not forget than when the ide drivers were updated, that -too- was
referred to a service pack or service upgrade.
Let's not read more into this (Boing Bag) than what I mentioned, ok? Heh!

No update 5 planned. We fly directly to the final version?

Well there were not plans to Update #4 tell last minute, but as there were no Hardware they did a update more.. same goes for update #5.. if there is no hardware I cant se them doing a final version.
