针对大量记录的java Camel restlet性能

Question

我使用的是camel restlet，它的响应记录约为500K。我遇到了性能问题，无法像这样传输大数据。交换过程大约需要300-400毫秒，而如果我在浏览器上查看时间，它将继续运行，如果我测量时间，它将在15-18分钟之间

你能帮我了解一下可能的问题吗？以下是json

{
   "BC":[
      {
         "internalCode":"B1C",
         "dgap":0.737940735389102,
         "gset":0.40132512265670084,
         "lastPrice":0.6980345629460734,
         "side":null,
         "insttype":"CBBC",
         "entitlementratio":0.506859210513693,
         "delta":0.1723159666242896,
         "logprice":false,
         "time":"02-10-2019 03:38:42.122"
      }
   ]
}

路线是这样定义的

<get uri="/getAnalyticsReport?synchronous=true&amp;streamRepresentation=true"  bindingMode="off" >
                <to uri="direct:analyticsReport" />
</get>

这是我测量的，大约需要300毫秒

我也试着获取堆栈跟踪，这看起来像堆栈跟踪
