    Too many variables to compare. No idea what those settings even do. Let's try something simpler. Ignoring all of the odd governor settings, here are logs for a Pixi that uses only constant speed profiles.

    Once again, from a fresh boot at 600MHz, switched to 768, things are fine. When switching back to 600MHz, the launcher begins to lag and skip significantly.

    You know what the most bizarre thing is? Downclocking to 480MHz actually makes the launcher UI run smoother than at 600MHz. I have tried this a few times now and I'm not imaginging it. After overclocking to 768MHz, the launcher UI will perform better when downclocked to 480MHz than when downclocked to 600MHz. That is interesting.

    I wonder what is changing how the phone performs at 600MHz. Gentlemen, good night.

    Assuming my observation is correct, there is really no reason for people to argue about tickle values and powersave biases. We are just wasting time talking about them, when to me it seems that the UI slowdown issue has nothing to do with those values.

    Great investigation. Can anyone else confirm the reported behaviour on their device? It is really important to be able to replicate results across a number of devices before we act on them.

    I have no idea what would cause something like that.

    Hmm. I'm not seeing it. I lag at 600, 320, and 480. All after fresh reboots. Although, I did boot from 480, change to 787, rebooted and it FELT smoother, but very minimal.

    You have lag, even on boot, even when set to the default profile?

    You have lag that is more significant than before you installed Uberkernel/Warthog?
    Where is the lag? Is it in the launcher, in apps, in card view?

    Sorry for the cross examination, but I'm curious.

    EDIT: For me in general, apps - the scrolling, animation, etc - only become slower than usual [which includes the usual occasional of jerkiness on a Pixi] once I downclock to 320MHz. Even at 480MHz, as long as I'm not doing too much, *apps* on the phone seem reasonably responsive.]

    It was scrolling through the launcher. It lags, but not extremly bad, i could deal with it. but 787 seems more smoother to me.

    confirmed, every freq from 320 to 787 on perf works smoother than 600.

    Wow, I'm starting to see it now. 600 Is laggy, more than compared to 320,480, and 787. 787 Is the best setting thus far for me. It seems like its near perfect.

    So I can confirm, that 600 is the laggiest out of 320, 480 and 787.

    Can everyone please be explicit about which governor (ondemandtcl or performance) they are referring to when they state a frequency?

    As with my post above, I will now only use performance when I post a log here, including when using 600MHz at boot. machjeff also says "every frequency...on perf".

    OK, what I am most interested in at the moment is whether and how people experience this lag with the default ondemandtcl governor and parameters.

    Noted. Keep in mind that my lag issues only occur when I switch *back* to default profile (with default parameters) after overclocking above 600. Simply booting with the default profile is not sufficient.

    So I now experience lag when I try both approaches.

    1. default profile (ondemandtcl) --> overclocked ondemandtcl --> default profile
    [with all other parameters default]

    2. performance600 --> overclocked performance --> performance600

    I apologize for not posting more logs, but my results haven't changed.

    very nice work guys can't wait till this is ready for the main streem any idea when it may be ready?
  16. #516  
    I hope this isnt true, but I have a feeling this project will be dropped sooner rather than later because of the pre2 coming and they wanna figure it all out asap. =( So, we may be stuck w/ the performance we have.

    BTW, I think my best results in OC are when I use performance gov both set to 787mhz
    Compcache disabled.
    I rarely get UI lag, and I thnk when I do get UI lag, is probably when the system has to deal with any sort of swapping to either swapfile or compcache. Either way, I believe thats the case...but cannot say for sure, it seems to be slowest when it hits the RAM limit and starts having to swap data out.
    But reading older data , even swapped data there is not any lag.

    I decided to stick w/ swapfile for now, no compcache simply because, using 16MB of RAM for compcache drastically takes away from actual operating RAM...which seems to be what the phone wants. Instead of having to swap.


    Lets just say the lag I experience now is comparable to stock kernel, it happens every once in a while. But the performance increase as far as loading webpages / loading programs has improved when using OC kernel.

    I also am using a value of 30 for vm.swappiness
    and using scheduler kernel parameters of the latest uberkernel...on the warthog kernel via a bootup script.

    GenTarkin-- what do you mean by 'swapfile'? is that just not having compcache?

    ok, thats what I thought. I too have been running overlclocked with ondemandtlc and compcache disabled, and it seems to me snappier than with compcache. its such a minor difference though, it might all be in my head.

    New bee here but thanks t our eazy steps i think i too can get it
    will try the same dont have cables update tomorrow
