This is before tweak

This is after tweak
Write speed didn't increased much but read speed is increased significantly.
Performance also increased.
Goto
/sys/devices/virtual/bdi/179:0/read_ahead_kb
And change value from 128 to 4096
Use sd tools to test it.
Remember to post ur screenshot here.
Post before tweak and after tweak screens here
Use 2048 for best results
Hit thanks if helped
 
I am using it since month

It increses read speed , little increment in write speed


Problem with this is
Every time you reboot your device you have to apply the values again
For this I am asking rom developers to add sd speed increase tweak in roms

It will not change anything.
The maximum change occurs is till 4096 only.
It will come to 128 again after the boot.
