, Facebook provides us with a test case, and we also use it to successfully improve our code. In the end, the same test case will be displayed in the following test score results ;-)
This test is performed in standalone mode. (Including servers and clients running on them ). So we use the largest HW box in our lab-a 48-core machine. This server can quickly point out an existing or potential performance bottleneck (most of them are on the memcached cod

This chapter focuses on the hardware abstraction layer:HAL. Hal is built on Linux Drive A set of libraries,Google for Android to join HAL mainly for the purpose of the following. 1. Calling interface for unified hardware2. Fixed the issue of GPI copyright 3. For a number of special requirementsIn the LED driver, we joined HAL to use the program does not need to care about the Linux driver and device files interactive way.
