    Default ICS bionic lag coming out of standby

    I have noticed that when the phone comes out of standby there is a soild six seconds of very high CPU utilization. This starts immediately after the power switch is pressed and is independent to when the phone is unlocked via the lockscreen.

    During this time there can be a lag pressing any buttons. After about six seconds everything is very snappy. I am wondering if this behaviour is what people are referring to when discussing ics lag.

    If I overlay the CPU utilization on the screen it looks like it is the os itself with no obvious reason.

    Has anyone seen or experienced this?

    Default Re: ICS bionic lag coming out of standby

    Just using the free Android Assistant, I see a couple of seconds that spike up to around 40% of usage, but it quickly calms back down to a couple of percent.

    I performed a "wipe cache" from recovery and I don't notice the lag like I did before. However, the CPU is still running high for six seconds. I looked in the event log and saw a bunch of log events like the following that go on for the entire six seconds.
    11-24 09:00:22.936 I/am_kill ( 376): [8581,com.googlecode.android.wifi.tether,11,too many background]

    Looks like it is saying there are too many background processes. I went into settings->developer and reduce from the default to 4 with not change. I have quite a few apps frozen already. I will continue to freeze all that I don't need.
