It would also be interesting to look at the log dumped by logcat with a
fresh rebooted nexus one. Would someone share here? Thanks.

Sorry I don't have a boot chart handy. Most of what I look at is the time
to the various log events representing key points during system boot.

Hi,
Please correct me if I am wrong. Can we reduce the booting time by
writing the code in assembly which copies the kernel and file system of
android to memory.
Thanks Regards

Hi ,
We are actually working on regular boot time optimization only. The stats
logcat output that I share was for regular boot of Android on OMAP3430.
So the stats does not represent the factory reset boot, the very very first
boot of phone.

As Dianne mentioned, its more appropriate to profile regular boot time, and
not the factory reset boot, the very very first boot of a phone, which's a
special for many modules..

Hi, We are working on Android boot time reduction.
We use OMAP3430 Board as our Hardware. Android version is 1.6 Donut.
We used bootchart to visualize boot pattern. From it, we found that
following things take bulk of time.
1.Zygote process. It actually do the proloading of java classes that
There is no trivial way to reduce either of those. The zygote class
preloading is essential for good performance of the system after boot. The
package scan can in theory do some caching of its results after first boot,
but this is a lot of work and has the potential to introduce serious bugs if
