    Since launch day, I have found that my Pre would get randomly slower/laggy for up to a few days at a time then speed up and get really smooth. I always thought this was a CPU bug but it seems I may have finally found the problem: the phone very often creates log files of apps and system tasks in the background, and this sometimes causes noticeable slowdown. I tried setting the logging to "minimal" and have had a VERY smooth Pre for the last few days. It's so smooth for me in fact that I've actually disabled all overclocking and am back to running at 500mhz! Here are the steps to do this, and bear in mind this is permanent unless you doctor your Pre. I haven't noticed any caveats at all since doing this, only performance improvements!

    1. Open the phone dialer.
    2. For Sprint/Verizon/CDMA: Dial ##5647 (##LOGS) and press SEND. For AT&T/O2/GSM: Dial #*5647# and press SEND.
    3. Tap "Change logging levels."
    4. Tap "Set logging to minimal."
    5. Tap OK to confirm.
    6. Tap OK again after it finishes.
    7. Reboot your Pre.
    8. Enjoy the performance boost!

    Please try this and post any feedback!
    Does anyone understand the mechanics of this?
    where does the change occur ? Phone? Network? Palm Profile? (i guess the latter)
    who collects those logs?
    What does the GPS (check the menu on that card) have to do with it?

    This dial sequence can do more then just changes log level..

    It will be good to understand that better..

    Try going back to the "Use Log Profile" screen and tapping "Restore Base Profile" and reboot.

    You shouldn't have any problems.

    I did it... can't say I notice much of a difference. Swiping up to unlock seems snappier and App Cat. seems a bit smoother. Video app opens fine.

    Just did this on a regular GSM Pre, and I thought my GovNah was in screenstate.
    It wasn't!
    So I enabled it, and swoosh!

    feels good so far. we will see if this will have any ill effects

    Has anyone cleared the logs too? I was thinking of doing that..

    I tried clearing them but didn't notice any extra changes, but some people might.

    Clearing the logs clears any log file dumps that may be stored on your internal/media drive.

    If you have never created any log files there would be none there.

    ok, I hardly ever post, but this is just worth it!

    I did this mod thinking, oh yeah, another 'tweak' that wont do much. I was so wrong! This really makes a difference. Anytime you're in a window that has you swiping 'back' often... such as browsing new apps in preware, or whatever, there used to be a delay after swiping back, before you could scroll down the list. My first 'scroll-grab' would always be ignored, then the second one it would go. Now it just goes right away!

    text, email, photos, all the apps are faster and more responsive.

    highly recommend this mod to anyone with this phone!

    Ya know, I'm starting to think this is working better than I initially thought... I've popped open the app catalog several times to check for a particular clock update, and not once has it bogged. Plowing down the installed app/update list always seemed to be the kiss of death for getting a severe system lag and browser gray-out/refresh. I'm liking this.

    Seems snappier indeed Great tip!!

    Thanks for the GSM hash! I just did it and must say I'm not feeling any difference in normal usage; if anything, scrolling seems laggier than usual but this could have any number of other reasons.

    I will however say that the Preware comment up there is right on the money - for whatever reason, Preware really seems to fly now. Maybe it likes to create logs in the background?

    Glad to see all the success stories!

    Do you happen to have a lot of text messages or a large call log?

    The CollectLogs app (see /usr/palm/applications/com.palm.app.collectlogs for the source code) is an interface to the palm://com.palm.logctld service which is implemented by the /usr/bin/logctld binary. It is a mojo interface to the PmLogCtl command which you can run on the Linux command line to adjust the logging levels of various system services and applications. WebOS Internals developers often use it to turn on debug logging for system services to see what they are doing behind the scenes.

    Here is the normal state of logging from PmLogCtl:

    root@palm-webos-device:/var/home/root# PmLogCtl show
    Context '<global>' = err
    Context 'BluetoothMonitor' = debug
    Context 'CertMan' = err
    Context 'CertMan.certHandler' = err
    Context 'CertMan.connectionMgrHdlr' = err
    Context 'CertMan.downladHdlr' = err
    Context 'CertMan.helper' = err
    Context 'CertMan.serv' = err
    Context 'com.palm.wifi' = err
    Context 'com.palm.wifi.supplicant' = err
    Context 'LunaDownloadMgr' = err
    Context 'LunaSysMgr' = err
    Context 'LunaSysMgrJS' = err
    Context 'media' = err
    Context 'netcfg.lib' = err
    Context 'netcfg.mgr' = err
    Context 'netcfg.mgr.conman' = err
    Context 'netcfg.mgr.fw' = err
    Context 'netcfg.mgr.ifnamer' = err
    Context 'netcfg.mgr.luna' = err
    Context 'netcfg.mgr.nwatch' = err
    Context 'netcfg.mgr.route' = err
    Context 'netcfg.mgr.tools' = err
    Context 'passthrud' = info
    Context 'PmBtContacts' = debug
    Context 'PmBtEngine' = debug
    Context 'PmBtStack' = debug
    Context 'PmLogCtl' = debug
    Context 'powerd' = info
    Context 'TIL.CCP' = err
    Context 'TIL.LOG' = err
    Context 'wan.auto' = warning
    Context 'wan.blade' = warning
    Context 'wan.cdb' = warning
    Context 'wan.connector' = notice
    Context 'wan.dss' = warning

    Context 'wan.pdpslot' = warning

    The Clear All Logs option does the following:

    #!/bin/sh

    echo Clearing all logs

    cat /dev/null > /var/log/messages
    cat /dev/null > /var/log/telephony.log
    cat /dev/null > /var/log/til.log
    cat /dev/null > /var/log/ccp.log
    cat /dev/null > /var/log/uploadd.log
    cat /dev/null > /var/log/powermond.log
    cat /dev/null > /var/log/kern.log
    cat /dev/null > /var/log/batteryapp.log

    rm -f /var/log/kern.log.*
    rm -f /var/log/powermond.log.*
    rm -f /var/log/messages.*
    rm -f /var/log/bt/*
    rm -f /var/log/gpsfix*.csv

    rm -f /var/log/*.gz

    cat /dev/null > /var/luna/data/MailLog.txt

    cat /dev/null > /var/lib/software/omadm.log
    cat /dev/null > /var/lib/software/sprintd.log
    cat /dev/null > /var/lib/software/updated.log

    rm -f /var/touchpaneldump/*
    rm -f /var/minicores/*
    rm -f /var/javadumps/*

    echo REM: Flushing all logs to disk, just in case
    PmLogCtl flush
    The only negative effect turning off logging can have is that if your device has a problem, Palm will not be able to help you diagnose the problem. Also, if your device has an application or operating system crash, Palm won't get any information in the automatic diagnostic upload that happens in those circumstances.
