Woah!

Something's happening!

Or am I getting over excited?

More speed improvements for an already efficient OS.

The article is very good reading for people interested in technical details. It's great to read about these improvements and that virtual memory is now finally integrated into the OS.

So when can I use the new memory system on my A1? Articles like these makes me wish I was on the beta list.

You are getting overexcited. Just read the "specialists" words some days later and you'll see what I mean.

Nice. I have one question though. It seems to be possible to use virtual mem e.g. in form of a file on disk now.

Are there any plans to support memory mapped files now under OS4 ? (e.g. the dos.library allowing you to "allocate" a mem image from disk ?) That would be great.

@Dr. Hirudo

It's good to see improvment in the operatyng system why you say so ?

Nope. Go nuts. Shave your head. Now is the time to freak out.

@all
The term virtual memory is often confused with memory swapping...

The above link might help explain things a bit further.

@ssolie

And indeed there's much to freak out for given that we poor humans don't have the luxury of enjoying the new memory system nor can update #5 at the horizon


@Rogue

Great (not just the article, I mean )! Thanks!

Reading this has me very impressed Hyperion has done it again! Great work guys!

Even more impressive is that it says when booting up Workbench with this new memory system, it should be using less than 2KB in all!!! That's pretty much awesome!

Hyperion? When to see a video footage of this performance from the new memory system?

@ Betatesters

Is the speed increase in general use really noticeable?

Keep the good work Hyperion and all OS4 developers.

I think that was only an illustration of how impressive the new memory system is. It's mentioned on the last part of that article from Hyperion, guys...

@Helge:

Read it again carefully, it doesn't say anything about memory consumption after booting, it just says that small allocations (below 8kb) takes a lot less time than before, thus making the whole system faster.As an example he provided the amount of such allocations during the boot process, allowing you to figure the speed increase.The memory consumption will stay the same.

@Helge

Did you have algebra in school? Paid attention, too?

Quote:
The time for a memory allocation is now in the order of a few microseconds. This is especially true for small allocation (below 8 KB). To give you an idea: When the system has booted up to Workbench, there have been already 40000 allocations to the global memory pool below 2 KB.

How do you get 2kb as result out of this calculation???

I think you should read it again.

Of course we should by now alredy know that there are no other specialists but Hyperion, and also that the world is black and white and... yada yada... :-p

is hard to notice a speed increasing at this state even bacause many things are not optimised yet
