Init.d TWEAKS

  

HOW TO ADD:-
-->>For adding init.d tweaks you must add init.d support from kitchen by using option "14" then you will see a new folder will be created under system/etc/"init.d"
-->>Now open a empty file with notepad++ and add- " #!/system/bin/sh " at top and then add below lines then save it with name as you wish.Make separate file for each tweak.
[*]Strict minfree handler tweak

Code:

echo "2048,3072,6144,15360,17920,20480" > /sys/module/lowmemorykiller/parameters/minfree

[*]Internet speed tweaks

Code:

echo "0" > /proc/sys/net/ipv4/tcp_timestamps;
echo "1" > /proc/sys/net/ipv4/tcp_tw_reuse;
echo "1" > /proc/sys/net/ipv4/tcp_sack;
echo "1" > /proc/sys/net/ipv4/tcp_tw_recycle;
echo "1" > /proc/sys/net/ipv4/tcp_window_scaling;
echo "5" > /proc/sys/net/ipv4/tcp_keepalive_probes;
echo "30" > /proc/sys/net/ipv4/tcp_keepalive_intvl;
echo "30" > /proc/sys/net/ipv4/tcp_fin_timeout;

echo "4096,16384,404480" > /proc/sys/net/ipv4/tcp_wmem;
echo "4096,87380,404480" > /proc/sys/net/ipv4/tcp_rmem;

[*]Vm management tweaks

Code:

echo "4096" > /proc/sys/vm/min_free_kbytes
echo "0" > /proc/sys/vm/oom_kill_allocating_task;
echo "0" > /proc/sys/vm/panic_on_oom;
echo "0" > /proc/sys/vm/laptop_mode;
echo "0" > /proc/sys/vm/swappiness
echo "50" > /proc/sys/vm/vfs_cache_pressure
echo "90" > /proc/sys/vm/dirty_ratio
echo "70" > /proc/sys/vm/dirty_background_ratio

[*]misc kernel tweaks

echo "500" > /proc/sys/vm/dirty_expire_centisecs
echo "1000" > /proc/sys/vm/dirty_writeback_centisecs

[*]EXT4 tweaks (greatly increase I/O)
(needs /system, /cache, /data partitions formatted to EXT4)

Code:

tune2fs -o journal_data_writeback /block/path/to/system
tune2fs -O ^has_journal /block/path/to/system
tune2fs -o journal_data_writeback /block/path/to/cache
tune2fs -O ^has_journal /block/path/to/cache
tune2fs -o journal_data_writeback /block/path/to/data
tune2fs -O ^has_journal /block/path/to/data

[*]Perfect mount options

Code:

busybox mount -o remount,noatime,noauto_da_alloc,nodiratime,barrier=0,nobh /system
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /data
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /cache

[*]Flags blocks as non-rotational and increases cache size

Code:

LOOP=`ls -d /sys/block/loop*`;
RAM=`ls -d /sys/block/ram*`;
MMC=`ls -d /sys/block/mmc*`;
for j in $LOOP $RAM
do
echo "0" > $j/queue/rotational;
echo "2048" > $j/queue/read_ahead_kb;
done

[*]MicroSD card speed tweak

Code:

echo "2048" > /sys/devices/virtual/bdi/179:0/read_ahead_kb;

[*]Defrags database files

Code:

for i in \
`find /data -iname "*.db"`
do \
sqlite3 $i 'VACUUM;'; 
done

[*]Remove logger

Code:

rm /dev/log/main

[*]Ondemand governor tweaks

Code:

SAMPLING_RATE=$(busybox expr `cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_transition_latency` \* 750 / 1000)
echo 95 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo $SAMPLING_RATE > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate

[*]Auto change governor and I/O Scheduler

Code:

echo "vr" > /sys/block/mmcblk0/queue/scheduler
or
echo "sio" > /sys/block/mmcblk0/queue/scheduler

[*]Governor (Best: Minmax > SavagedZen > Smoothass > Smartass > Interactive) - needs kernel with these

Code:

echo "governor-name-here" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

[*] Disable normalize sleeper

Code:

mount -t debugfs none /sys/kernel/debug
echo NO_NORMALIZED_SLEEPER > /sys/kernel/debug/sched_features

GPS.conf TWEAKS

  

How To:-Create or edit your /system/etc/gps.conf with a Notepad++.
Benefit:-For improving GPS lock time and signal.

-->>SE supl for A-GPS (better than Nokia's or Google's)
