I agree about the memory problems in flash. But next generation smartphones will be having SSD's.. Not much restriction on number of writes plus access time. and samsung and toshiba have already started with the release.
http://www.trustedreviews.com/news/Toshiba-Reveals-128GB-Smartphone-Flash-Memory and even with better compression techniques like lzma that compresses 33% more than that of gzip. and with processor's like snapdragon and hummingbird (both 1GHZ now and will be more powerful in future) that can uncompress the images faster than ever shouldn't the focuss must be given here. Its just an opinion. As u mentioned previously and i even went through your presentation at LinuxCon North America, August 2010 that said more boot time is consumed in user space portion of boot. But i suppose even if we do optimize some start up services or package scanning or network initialization delays.. In future there are going to be more packages no doubt.. and there might be a case where u cant optimize it further and still the boot time is more. So shouldn't we try what these *Ubiquitous QuickBoot did and make it opensource as Quickboot is not* On Wed, Aug 24, 2011 at 11:35 PM, Tim Bird <tim.b...@am.sony.com> wrote: > On 08/24/2011 10:54 AM, NilesH Somani wrote: > > Thank u sir > > So basically the init process slow downs the android boot up time.. > I would word it differently.
