Abstract
Implementations of this specification provide a method, an apparatus, and an electronic device for improving performance of a central processing unit (CPU) comprising a plurality of CPU dies. The method includes the following: enabling threads in each CPU die of the CPU to compete for a mutex of a respective CPU die; identifying the plurality of threads that have obtained the mutexes; enabling the plurality of threads that have obtained the mutexes to compete for a spin lock of the CPU; identifying, from the plurality of threads, a target thread that has obtained the spin lock; executing a critical section corresponding to the target thread that has obtained the spin lock; and releasing the mutex and the spin lock that are obtained by the target thread.
