Hi, I have moved from HTC Tornado to Samsung i600 (with WM6), and I think that it kills background applications very eagerly:

For example, on HTC Tornado I could run JVM (opera mini), media player, browser, IM, OneNote Total commander and even though the memory was almost full, everything worked, and I could return to a page in opera mini after a day of other work (and it still had just 24MB of free RAM after fresh start).

Not so on i600, usually running WMP and IE is enough to get JVM in background killed, even though there's enough (12MB+) of free RAM. I think that it kills background tasks too eagerly...

I did know about a registry key that changes memory manager's behaviour, but I cannot google it (no matter the phrase I use, I get mostly task-manager tools).
Can you remind me of correct registry path? Thanks!

I found http://forum.xda-dev....&postcount=228 , but it is only for HTC devices (I don't have the HTC reg key). And http://forum.xda-dev...ad.php?t=373128 discusses this as well, but again, no solution for non-HTC phones.

Need to understand how Google works :)

Seriously though I find any search engine a pain from time to time but this time I used "windows mobile registry key memory managment"
and came up with this MoDaCo result in the top few results. Scroll down the page to find a section on file cache size

Hmm, it should be this: http://www.howardfor...c/540062-1.html

Trying to make the best of both worlds, I decided that perhaps the MPx220 is worth taking another look at if the memory management issue could be resolved. After all, with Media Works, I want to keep Agile Messenger open all day to receive IMs, while using the phone, surfing, playing games, etc.

Then, it dawned on me - why is the Audiovox SMT5600 with an apparently older revision of WM2K3 running things better than the newer MPx220?

A couple of registry keys.

MPx220:
[HKEY_LOCAL_MACHINE\Software\Microsoft\Shell\LowMem ]
"ResetDivision"=dword:1
"ProgramMem"=dword:32

SMT5600:
[HKEY_LOCAL_MACHINE\Software\Microsoft\Shell\LowMem ]
"ResetDivision"=dword:0
"ProgramMem"=dword:96

After forcing in the SMT5600 settings on the MPx220, I ran Agile Messenger and connected. Then, I ran Internet Explorer. Launched Agile again, and same copy of Agile still came back, still connected. Launched MSN Messenger. Launched Agile again, still accessible and running. Launched Tasks, Contacts, Calendar, File Manager, Resource Management. Returned to Agile Messenger, still running! With all these programs running simultaneously, Agile Messenger is still active and connected!

With the original registry settings, Agile Messenger would get lost in the memory and a new instance of Agile Messenger would launch, and not be able to connect because the original copy was still connected.

I was looking for the LowMem key, fortunately I remembered that I had these problems years ago on Moto mpx200, so I added mpx 220 to the search, and got what I needed... still thanks for help :)
