Another interesting project from Freemangordon

What's the reason for moving the Qt libs to rootfs? Is it a packaging reason, technical cause, performance or... I could not find that in the easlier posts. And can I move it back to opt using a symlink afterwards if I run low on space in rootfs?

Will definitely give it a try somewhere in the comming weeks.

The rationale behind moving Qt is that rootfs is faster than /opt, being a different and faster technology. I hope most of the rootfs space will be regained when more packages are thumb-compiled. And you can move it back (and symlink) to /opt if you wish

Ok so far im using 127MB before and after this...

But before i had a max memory of 240, now 230?
I can see in conky that all running programs (at same uptime as before) are using a little less memory so there is something here.

Submitting 2x screenshots, download and compare, alot of things are changed.


-


Now i have just installed this so i can't say about performance.

And followup: can i install powerkernel and OC?

a) this is basically KP50 and replaces it (for this purpose here)
b) freemangordon said the install can be forced for the current 'kernel-power-settings' package, but it needs to be updated

EDIT: come on, this thread is not even 2 full pages long and you are an oldtimer here

freemangordon: Can you give a little more info on the microb you tried to build.
Complete compile of microb or just the microb-engine?
Are the full sources (ui, microb-engine, browserd) now available?

Very impressive, and I did not install it no inconvenience, no errors detected, and apparently see better performance, applications are opened little faster, and do not stutter badly when multitasking. I look forward to new updates and the new compilation of microb.

One question you mention above about moving Qt libs to roofts, but my n900 have now 18.2mb (before updating had 36,1mb) in rootfs and Use moveroot.sh (script for tanner) http://wiki.maemo.org/User:Tanner#Re...ing_the_flash; and other command post to other roofts Cleanup ie; http://talk.maemo.org/showthread.php...ghlight=moving and Sifo script http://talk.maemo.org/showthread.php?t=84398&page=2, in the following updates are occupied more space in the rootfs? can I free more space for rootfs by other means?

Thank you and all community of maemo for keeping alive my n900.

rootfs is also compressed on the go which actually makes all that blessed speed gain negligible if not counterproductive. If someone opened up rootfs he would be a saviour (in speed dept and a blasphemer as what is now in rootfs will need a LOT more space to fit. I can put 10mb of .c/.h files and they will take around 500kb of it. With uncompressed rootfs no libraries/dev packages that's for sure).
One easy experiment is moving microb binary to opt and comparing starttime after kill. For me opted binary starts faster (lots of non-plaintext code to decompress), but probably biased. See for yourself, difference in size taken from rootfs vs claimed is easily confirmed, just copy a file there and compare. Since saving rootfs is the goal, crowding it with qt, no idea why

Hmm installed power kernel to OC, now everything crashes & getting internal error, FAM does not work.

Is there anyway to use the Thumb2 and OC, i can defiantly see a less memory impact vs my main N900, very little swap used so far, less then half.

Glad i have my extra N900 now to test with
