        self.proxies = self.load_proxies()
        self.performance_metrics = {}

    def get_optimal_proxy(self):
        return sorted(
            self.proxies,
            key=lambda x: (
                self.performance_metrics.get(x, {}).get(‘success_rate‘, 0),
                self.performance_metrics.get(x, {}).get(‘response_time‘, float(‘inf‘))

        self.fail_count = 0

    def adjust_delay(self, success):
        if success:
            self.success_count += 1
            if self.success_count > 100:
                self.delay = max(0.5, self.delay * .95)
        else:
            self.fail_count += 1
            self.delay *= 1.5
