What Is a TLAB or Thread-Local Allocation Buffer in Java?

Date: 2024-01-15

Java's Thread-Local Allocation Buffers (TLABs) optimize memory allocation in multithreaded applications. Each thread receives a dedicated memory area for object creation, minimizing contention and improving performance by reducing the need for global locks. This enhances parallelism and scalability. While TLAB size impacts performance, careful tuning based on monitoring and profiling can balance reduced contention with minimized memory footprint, ultimately boosting application efficiency.
