Same problem for me, I have just do a clean flash to see if there was related to a specific app. I my case sometimes after getting slower and slower the phone reboots itself.
This did not happen with stock kernel or EucOs kernel.

I tried the low memory killer with kernel adiutor. Checked out all the different profiles there, but it didn't help at all. After 10 hours, the phone was unusable until a reboot.

I wonder if the problem is hardware-related. Otherwise there should be much more people experiencing this slowing behaviour.

Congratulations!
And , happy new year!
Thanks for the wonderful kernel!
Now, for a scary question-
Is it possible that further changes in newer Android versions may become incompatible on Nexus 5 and then development will have hurdles?

@eng.stk any answer for this question?

Geez, its the holidays. Let him enjoy himself. ::D

At the moment no, because N5 doesn't have a Oreo tree, depends what they'll do.
There's some 8.0 changes that don't killl backward compatibilty, 8.1 can be a little harder. Not to mention they may decide use CAF trees, who knows.
N5 has some talented mainteiners, we'll have to wait and see.

So, for any android version, If you get a stable device tree, is it possible for us to recieve this wonderful kernel?

It is related to memory. As soon it reaches ~80% usage it gets laggy. Closing some recent apps frees memory and the phone gets usable again.
I have tried different memory profiles in Adiutor, and agreesive modes (not expected) seems to solve for now the problem. Light modes didn't solve it.

Indeed. I'm sporting Aggressive profile for some time now and its buttery smooth no problems whatsoever.

    Kernel features:
    • Build with custom toolchain blu_naro-7.2 (cortex-a15 neon-vfpv4 hard-float targeted, build with latest Crosstool-NG from developer snapshot Linaro GCC 7.2-2017.10)
    • Full -O3 support with device and target flags enhanced, linaro build improvements, etc
    • Less is more: stockish builds based on android-msm-hammerhead-3.4-marshmallow-mr3
    • Kernel compressed with XZ, custom tweaked RAMdisk with GZIP (faster boot times)
    • Removed some debug and logging options
    • Enhanced performance and battery patches
    • Several CPU Governors (blu_active own governor is default- fastlane mode available!)
    • Voltage Control UV_mV_table (UV down to 700mV possible)
    • Enhanced TCP methods (westwood is default), Network and Wifi tweaks
    • Several I/O control (added FIOPS and ZEN is default), tweaked filesystems (F2FS, ExFAT, NTFS & CIFS available)
    • Disabled stock mpdecision and thermald
    • blu_plug: Dynamic hotplug for hammerhead
    • msm_thermal simple driver (default 65º C threshold)
    • Optimized RWSEM, AES and SHA1 routines (with neon support)
    • Vibrator Strength tunable (60% default)
    • KGSL fixes and reworked GPU driver (removed doubled freqs, goes to idle @ 27MHz), Simple GPU Governor by default
    • Gamma Control and KCAL - Advanced color control for Qualcomm MDSS (RGB calibration and post-processing features)
    • Backlight dimmer ready (disabled by default, tuned min manual brightness - level 3)
    • Wakelock blockers available
    • USB automount (ROM must support it, otherwise use stickmount)
    • CDROM emulation added to mass_storage (Drive Droid compatible)
    • Kexec (multirom) full support
    • doubletap2wake available (0:disabled, 1:enabled, 2:enabled fullscreen), option to disable with power button or after wake_timeout
    • USB Fast Charge (USB mode up to 900mA with MTP, Increase battery charging current to use higher input current on AC mode, proprietary charger detection
    • init.d support (put your scripts in /system/su.d or /su.su.d [systemless SuperSU], /magisk/.core/post-fs-data.d [Magisk])
    • Compatible with Kernel Adiutor, Universal Kernel Manager and others

    DOWNLOAD KERNEL ZIP (no mirrors please)


    Warning: If you come from other kernel, you should dirty flash your ROM before flashing blu_sp★rk zip to avoid problems.
    Also uninstall or clean data of any kernel control app you're using.

    About bugs and troubleshoots: don't bother to post if a log isn't ready or without steps so the behavior can be replicated. Also, I only actively support stock ROM with NO mods whatsoever (apart from root).
    No support will be given to custom ROM including N stuff, so don't clutter the thread with it (specially):
    • No talking about WiFi and N issues.
    • No talking about ROM related and misc N issues.
    Save the SOT and battery stats/screenshots for general threads, here we deal with development, not personal tastes and results.
    Also no OT about OTAs, apps, ROM bugs and other userspace stuff. There's threads for it, use them.


    This kernel installer modifies your filesystem, backup your boot.img with TWRP if you want to go back to full stock (or you can fastboot boot.img or dirty flash your ROM also)


    If you want to use F2FS, do the following (backup your data before attempt this, it will erase all your Data)
    • Flash TWRP with f2fs support and flash latest blu_sp★rk zip
    • Go to Wipe -> Advanced Wipe -> Select only Data -> Repair/Format File system -> Change partition type to F2FS
    • Go to Wipe -> Advanced Wipe -> Select only Cache -> Repair/Format File system -> Change partition type to F2FS
    • Reboot and profit

    Code_Blue r923

    All right crew!

    Back to the heavyweight jam :angel:
    I decided to reopen the thread after some thinking and some nice talks I had with several people.
    I do this for fun, so behave and don't make me regret it.

    This is for Lollipop 5.1 ROMs only.

    The zip uses anykernel installer, this means it uses previously installed ROM kernel Ramdisk.
    If already have Code_Blue or ROM default kernel installed just flash over.
    If you come from other kernel dirty flash you ROM and flash Code_Blue after.
