vert.x - vertx 如何让后期处理程序更有效地工作

Question

我是 vertx 的新手，正在尝试进行测试以将一些遗留代码迁移到 vertx，以提高 qps 性能。但是我在迁移 post 方法时遇到了麻烦。

我尝试添加一些如下代码，我可以从请求中获取表单属性并获取处理程序工作

router.route().handler(BodyHandler.create(false));

.handler(routingContext -> {
         HttpServerRequest request = routingContext.request();
         request.setExpectMultipart(true);
         request.endHandler(end -> {
           // request.params().addAll(request.formAttributes());
           routingContext.next();
         });
})

但我发现qps迅速下降，处理程序在里面做mysql事务。
