Ok, so I've just gone from 2.3 to 2.4 & have a BIG problem.
Under 2.3 I had about 50% more RAM showing as available at idle.
This is causing big issues for me, due to lack of available RAM.
What is causing the "memory chewing"? Can I turn something off, or should I just go back to 2.3?

Just re-installed 2.3 & OWB 1.3 Lite.
Hello speed...much better!!!!

For the very brief time I had an Efika, I noticed OWB 1.5 was a monster resource hog and actually loaded pages slower than 1.4. And under OS2.4, out of the supposed 128mb available: only 79mb was left. Don't remember if OS2.3 was less hungry, but wouldn't be surprised. The Efika and MorphOS really do need more memory than 128mb.

Maybe it has to do with enhanced display settings and multibuffering. If that's it, you should disable double/triple buffering in prefs->display engine. But I'm not really convinced about that extra usage, anyway.
About OWB1.5, it actually requires less memory (and some leaks were fixed, too), and additionally, it also avoids crashing in a few low-memory conditions cases (not all of course, since webkit is hopeless about that).

Thanks guys, I'll have a bit more of a play around with it tonight.
Wish my Mac Mini wasn't used so much at home...I'd just put MorphOS on it!

I am having the same problem with MorphOS2.4 on my Efika using twice the memory than 2.3 did right after booting, with no applications running. I have re-installed the OS a few times now, but have not been able to track down the problem yet. I had thought that when I first installed MorphOS2.4, I actually had MORE RAM available right after booting my Efika, but I can't seem to get back to that configuration.
Fab, could using the G4 MacMini version of the MorphOS2.4 iso instead of the file download option during the Efika installation process make a difference? I mean maybe some of the files needed to make MorphOS2.4 work on the G4 MacMini are being loaded into memory on my Efika and this explains the use of RAM with my current MorphOS2.4 install on my Efika.
The download during the install process can sometimes take so long that the OS times out during the installation, if I am doing a clean install and not an upgrade from MorphOS2.3, so instead of doing the download of MorphOS2.4, I have pointed to the iso file that I used to install MorphOS2.4 on my G4 MacMini.

I always download the .iso first & run it from a flash drive or other partition...good move, saves a heap of time :)
Just put 2.4 on my Mac Mini...fark yeah!!!! It's fast & clean, I'm loving it!!!!

It appears to be the exact same image, so no go there...

@amigadave
Well, check what i said about display settings. I see nothing else that could affect efika in such a way.

Just stumbled onto something today that may be of relevance: GigaMem. Has anyone tried this on their Efika system? Wish I would have known I had it when I had my machine. Might have solved some of these memory issues. This program creates virtual memory from any mass storage device up to 1GB for an Amiga system...

I'm guessing it also requires an 68k processor with an MMU?

MorphOS 2.4 uses enhanced display as default, try to disable it in the MUI screen preferences you use for Ambient (uncheck the enhanced display tick). If you open system prefs you can also disable triple buffer and probably double buffer too.
Depending on the resolution you use it may be a good idea to switch to a 16bit display.
You'd better use Fab's webpage OWB Lite versions so you save some precious ram :-)
If you have a custom screen for OWB perhaps you could run it in the same Ambient screen to save some ram.
-

DOH! Yeah, that's right. This product is from '92 and the manual does state 020+. There goes that idea :( I was narrowly stuck in Workbench compatible mode. lol

Would there be any advantage to an MorphOs/Amiga vitual memory that used the USB connected flash drive sticks?
How about virtual memory using a sollid state "hard drive" ;compact flash 4gb cards are on sale periodically for $25 US.

Wouldn't be much of a fun. usb is very out of question being usb1.1 only (I get 800 - 900 kb/s on average). The hd is also not the fastest one can think of. It would just be a brake. Better watch your setup and mem usage.
I am fine on my Efika with MorphOS 2.4 and OWB 1.6 with one to three tabs, Songplayer, SimpleMail, an editor and Wookiechat all simultaneously. If I need more free RAM I use Sputnik instead of OWB. Works quite reliable, uptimes of more than a day are normal(then i switch the device off usually). After boot up I have about 80 MB available.
-
Well, I got a bit bored this afternoon & dug out the Efika for a bit of a play around.
Note that when I reverted back to 2.3 I completely wiped 2.4 .
Today I upgraded it from 2.3 to 2.4 just like last time, except this time it's working fine.
It would seem that there was something wrong with the way the last (troublesome) 2.4 install was working.
Anyway, it seems that everything is back to normal & 2.4 works great, so all that was needed was a reinstall.
I wonder what actually went wrong though...why would it have ate RAM like mad before, but after rinstallation it works fine? Quite odd really!

Maybe I wasn't clear: my idea was to use Compact flash or SD card adapter to replace internal mac mini hard drive .My understanding is these would be faster than 5400rpm hard drive;the Ultra III 4GB Compact Flash card I have states 30MB transfer rate.
i have order both CompactFlash and SDHC card adapters to 44 pin ide to try.

Huh? mac mini hard drive in an efika?

For efika I'm not sure those 30MB/s will help much, I think we're still dealing with PIO transfers on that, but of course seeks will be faster. And if you meant to post this in a mini thread, the HDD (5400 rpm) in my mini handles twice that transfer rate.
