+
+Set thread count to 8:

+#define CPPHTTPLIB_THREAD_POOL_COUNT 8
+```

+Disable the default thread pool:
+
+```cpp
+#define CPPHTTPLIB_THREAD_POOL_COUNT 0

+### Override the default thread pool with yours
+
+```cpp
+class YourThreadPoolTaskQueue : public TaskQueue {
+public:
+  YourThreadPoolTaskQueue(size_t n) {
+    pool_.start_with_thread_count(n);
+  }
+
+  virtual void enqueue(std::function<void()> fn) override {
+    pool_.enqueue(fn);
+  }
+
+  virtual void shutdown() override {
+    pool_.shutdown_gracefully();
+  }
+
+private:
+  YourThreadPool pool_;
+};
+
+svr.new_task_queue = [] {
