### Motivation When Netty's `EventLoop` receives a new task，it will call `eventFdWrite`, and then trigger system calls, such as: system_call_fastpath, eventfd_write After we replaced EventLoop with a native jdk thread pool, the performance improved ### Modifications Use ThreadPoolExecutor instead of EventLoop ### Verifying this change We use pulsar perf for testing before： Aggregated throughput stats --- 11715556 records received --- 68813.420 msg/s --- 537.605 Mbit/s after： Aggregated throughput stats --- 18392800 records received --- 133314.602 msg/s --- 1041.520 Mbit/s ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
