Adjust and Boost Your SD Buffered Read/Write Throughput Performance.

**REQUIREMENT** Rooted Phone and Root Privilege are Required Because This App Need to Change the Kernel Parameter of Your System.

Optimal setting:
1. read_ahead_kb: depends on your applications and memory size (512KB ~ 4096KB)
2. scheduler: deadline
3. fifo_batch: 1
4: nr_requests: depends on your memory size. may > 128

This app can adjust the SD card parameter "read_ahead_kb" in your Android Linux kernel setting. By setting the attribute, your mobile device and SD card read/write might gain better performance. The buffered read performance is highly correlated with running Apps on SD, browsing photo albums, etc. The write performance is not directly controlled by this attribute. By enlarging read buffer with reducing read action to SD, write command can be done more quickly and efficiently without being interrupted by multiple separate SD read command. On the mobile device equipped with less memory space, it's recommended not to set the buffer size larger than 1024KB. The larger buffer size is good but it might affect the available memory space used by other buffers and normal Apps. It could result in bad performance due to Android needs to kill inactive Apps and recovery memory frequently.

Also, you can set the App option to automatically enlarge the default system buffer on EVERY boot.

This app also has built-in performance testing feature. This does not actually reflect the real RAW SD read/write speed, but highly relative to your normal phone and Android usage because Linux OS has system buffer for file IO.

**NOTE** Android is multi-tasking OS and Java-like VM. Due to lack of REAL-TIME operation (and impossible to lock your phone to do real time jobs), the performance testing results might be affected by many factors, such as background tasks, App managers, Dalvik VM garbage collections, Android System and Google Services, and etc. If the testing result looks not accurate, please quit/kill some applications running in the background or accessing to SD, and perform multiple run to see the best one.

Questions & Answers

Q: What is an APK File?

A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.

Q: If I install an APK from this website, will I be able to update the app from the Play Store?

A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.

Q: Why ApkClean.net can guarantee APK 100% safe?

A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.

Q: What are Android App permissions?

A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
