将消息发送到服务总线主题花费的时间太长

Question

我正在从Azure函数向Service Bus Topic发送消息，当函数被调用前3-4次时，向Service Bus Topic发送消息大约需要10-20秒，我正在寻找减少这一时间的方法，我正在使用以下代码向service bus发送消息。

public class ServiceBusTopicService

    {
    private static ITopicClient _topicClient;

    public ServiceBusTopicService(string serviceBusConnectionString, string topicName)
    {
        _topicClient = new TopicClient(serviceBusConnectionString, topicName);
    }
    private  static async Task SendMessage(string json)
    {
        var message = new Message(Encoding.UTF8.GetBytes(json));

        await _topicClient.SendAsync(message);
    }

    public async Task BroadCastEvent(string matasId, Guid correlationId, string profileSource, string eventType)
    {
        var eventToPost = JsonConvert.SerializeObject(ProfileEvent.GetProfileEvent(matasId, correlationId, profileSource, eventType));
        await SendMessage(eventToPost);
    }
}

如果它只是在启动时，那么它很可能是cold start problem。
