I've got a suggestion - Dzo, default cache size for reading sdcard is only 128kb. If we put 2048 or even a great value, the read access will be improved.
The file is located at /sys/devices/virtual/bdi/179:0/read_ahead_kb
Could you please put 2048 or something as default? It improves really the read accesses. The problem is that when we reboot the phone, the value returns to default, so for this reason I'm asking to put the 2048 as default.
