Init.d
(needs ROM with init.d access and busybox, open empty file, insert header #!/system/bin/sh and put these there, save in /system/etc/init.d and name it something like 77tweaks)

1. strict minfree handler tweak

Code:
echo "2048,3072,6144,15360,17920,20480" > /sys/module/lowmemorykiller/parameters/minfree
2. 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 "404480" > /proc/sys/net/core/wmem_max;
echo "404480" > /proc/sys/net/core/rmem_max;
echo "256960" > /proc/sys/net/core/rmem_default;
echo "256960" > /proc/sys/net/core/wmem_default;
echo "4096,16384,404480" > /proc/sys/net/ipv4/tcp_wmem;
echo "4096,87380,404480" > /proc/sys/net/ipv4/tcp_rmem;
3. 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
4. misc kernel tweaks

Code:
echo "8" > /proc/sys/vm/page-cluster;
echo "64000" > /proc/sys/kernel/msgmni;
echo "64000" > /proc/sys/kernel/msgmax;
echo "10" > /proc/sys/fs/lease-break-time;
echo "500,512000,64,2048" > /proc/sys/kernel/sem;
5. battery tweaks

Code:
echo "500" > /proc/sys/vm/dirty_expire_centisecs
echo "1000" > /proc/sys/vm/dirty_writeback_centisecs
6. EXT4 tweaks (greatly increase I/O)
(needs /system, /cache, /data partitions formatted to EXT4)

a) removes journalism

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
b) 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
7. 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
8. microSD card speed tweak

Code:
echo "2048" > /sys/devices/virtual/bdi/179:0/read_ahead_kb;
9. Defrags database files

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

Code:
rm /dev/log/main
10. 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
11. Auto change governor and I/O Scheduler

a) I/O Scheduler (Best: MTD devices - VR; EMMC devices - SIO) - needs kernel with these

Code:
echo "vr" > /sys/block/mmcblk0/queue/scheduler
or
echo "sio" > /sys/block/mmcblk0/queue/scheduler
b) Governor (Best: Minmax > SavagedZen > Smoothass > Smartass > Interactive) - needs kernel with these

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

12. Move dalvik-cache to cache partition (if it's big enough) to free up data partition space

Code:
CACHESIZE=$(df -k /cache | tail -n1 | tr -s ' ' | cut -d ' ' -f2)
if [ $CACHESIZE -gt 80000 ]
 then
 echo "Large cache detected, moving dalvik-cache to /cache"
 if [ ! -d /cache/dalvik-cache ]
  then
  busybox rm -rf /cache/dalvik-cache /data/dalvik-cache
  mkdir /cache/dalvik-cache /data/dalvik-cache
  fi

 busybox chown 1000:1000 /cache/dalvik-cache
 busybox chmod 0771 /cache/dalvik-cache

 # bind mount dalvik-cache so we can still boot without the sdcard
 busybox mount -o bind /cache/dalvik-cache /data/dalvik-cache
 busybox chown 1000:1000 /data/dalvik-cache
 busybox chmod 0771 /data/dalvik-cache
 else
 echo "Small cache detected, dalvik-cache will remain on /data"
fi
15. Disable normalize sleeper

Code:
mount -t debugfs none /sys/kernel/debug
echo NO_NORMALIZED_SLEEPER > /sys/kernel/debug/sched_features
1
GPS.conf
(create or edit your /system/etc/gps.conf with a file manager with root access)

For improving GPS lock time and signal.

a) European NTP server (replace for america or asia in your case)

Code:
NTP_SERVER=europe.pool.ntp.org
XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
b) SE supl for A-GPS (better than Nokia's or Google's)

Code:
SUPL_HOST=supl.sonyericsson.com
SUPL_PORT=7275

Other tweaks or guidelines

1. Patch your hosts file for blocking Ads
(please think before doing this; many developers are supported through this way)

Code:
You can use AdFree application for this or changing manually your hosts file.

Here are some databases:
http://www.mvps.org/winhelp2002/hosts.txt
http://pgl.yoyo.org/adservers/serverlist.php?showintro=0;hostformat=hosts
2. Use CyanogenMOD's APN list file - it's one of the most complete.

Code:
It's located in /system/etc/apns-conf.xml
3. Use UOT kitchen for basic theming on your device.

Code:
http://uot.dakra.lt/
4. Use Google's dns servers

Code:
Create an empty file, name it resolv.conf and put there these 2 lines:
nameserver 8.8.8.8
nameserver 8.8.4.4

Save to /system/etc/.
5. Update Superuser and su binary to latest version (3.0 beta)

Code:
http://goo-inside.me/superuser/
7. Do not use task killers.


Alright, I think this is it for now.
If you have any other tweaks or better values, you can comment below and I'll include them.


To edit the above use Root explorer

Thanks to knzo for providing the tweaks....

Comment Below if you have any doubts....

Note : I'm not responsible if u brick ur Device.
