ivgavez: like your idea. would be better maybe to rework microb if we have the full source yet. that way more people would be able to compare to something the have used. any improvements could then be rolled into cssu or extras.

Gecko is a dog, true, but most of its footprint is data so the ISA won't make much difference.
I suspect any significant performance improvements will only materialise after at least the most commonly used libraries and the X11 stack have been rebuilt. Until then most processes are going to be switching between ISAs all the time (and dropping the BT caches to boot).
Cf http://syslog.movial.fi/archives/46-...ot-to-VFP.html (currently down, archive copy here).

i would definitely add a warning that one needs at least ... free space on rootfs. /cleaning up right now

. BTW I thumb2 compiled microb, and the difference in code size is about 7-8 MiB, which is a HUGE difference, having in mind browserd is always running. Unfortunately I was unable to run that binary and didn't have time to check why it aborts. microb will be my next favourite for thumb2 compilation once what is done so far is proved to not bring problems@don_falcone: yeah, will add such a warning once I am back home, the reason is that Qt libs (being much smaller) are moved to rootfs from /opt. Theory says we sholud have an additional performance gain for Qt applications if libs are on faster NAND (NOR or whatever
)

Can i remove kernel-power afterwards? Especially the modules?

@Mohammed Muid: yes, what we're discussing with don_falcone is something in the range 10-15 MiB

...too little, give some slack and say 25Mb at least. I had 4MB free and was forced to temporarily move out 'beta' theme, locale-archive, dsp libs, nokia-maps, poker-th, and so on & on. Afterwards the upgrade i had 152kB left
