彭博社网络服务对单个字段和单个仪器的调用耗时超过1分钟

我正在为"DEBT_TO_EQUITY_FUNDAMENTALS_TKR"字段调用Bloomberg web服务GetData。我将secmaster设置为true，并要求一个具有CUSIP标识符的单一工具（带有yellowkey=MarketSector.Corp）。

在我看来，这是一个相当轻松的电话，因为人们同时要求数千台仪器和数十块田地。

我已经设置了很多不同的设置，但我无法在几秒钟内返回这个请求。它给了我正确的返回值，但它需要60秒以上的时间。

你知道是否有可能在几秒钟内执行并返回这样的请求吗？

感谢

编辑-这是我正在运行的代码：
