a couple of things i have experienced after some time of use now.
1. maemo loves to crash all running programs if ram+swap gets maxed out.
2. i can't see any change when using ramzez to change from 10% to anything else, and that ramzez defaults back to 10% rather then showing the current setting used adds to the confusion...
hmm, it would appear that a reboot is needed to apply the ramzez settings change...

hey locusf
I'm having a problem installing your application. I've gone to the garage and clicked on the ramzez 0.3 diablo armel.deb I'm getting incompatible application package. can u give me a hand?

I do not understand. 10% of what? You have to specify the uncompresed size, then it will use the ram it needs to hold the compressed pages.
Why reboot? "/etc/init.d/ramzez restart" is enough

there is a gui program that allows one to select a percentage of ram one want to use. Options are 10, 20, 25, 30, 50.
The "crashes" were caused by the linux kernel killing processes because running out of memory. You had only 13MB uncompressed (10%) of swap, so any memory hungry program you ran and BAM!, out of memory.
I recomend you adding a 64 MB swap file, since ramzswap also consumes memory and reduces available ram, and in my usage experience it is easy to start using those additional 64MB (running mediabox, tear and a couple of xterm is enough)

kinda funny, as maemo have earlier warned about low ram, and suspended operations. But these "crashes" are something new.
meh, i think i'll stick to about 24MB swap on the card, as that seems avout enough to not get problems with tear trying to swap itself or something.

I have found that maemo usually swaps out about 40MB of rarely used ram pages. That's why I insist in 64MB, and for that reason 24MB is certainly a too small swap size to maximize performance.
By using ramzswap you win speed and responsiveness when reading those pages back (switching programs), and much reduced mmc wear (if that bothers you), at the cost of a little less ram.
Just try several settings and find what maximize performance for your usage. As I already said, 64+64 is ideal for me.
"free", "cat /proc/swaps" and "cat /proc/ramzswap" will provide you with all information you need

the 24MB allows the system to swap out the least used stuff, while at the same time it will not make maemo start swapping to much when tear goes loading one heavy page to many, without having everything shut down on me like ramzez do right now no matter what setting i use for it.
if i have to use ramzez alongside a normal swap area, i can just use the normal swap and ignore ramzez, as i was hoping that ramzez would allow me to forgo ordinary swap...

I guess maemo monitors the swap file by name (haven't tryed with a swap partition), and that's the reason the kernel shuts down apps instead of maemo giving a warning.
About the 24MB, what I'm trying to tell is that if you up the swap file size to 40 MB, maemo still won't have enough space to swap too much, while maximizing the available ram.

Fails to install Ramzez .3 or .2 on N810 WiMAX 5.2008.43-7.
Is there a fix for this?
Code:
Error "Status: Not installable. Unable to install ramzez, Incompatible application package".
