随着Windows Phone 7.1不佳UDP性能（芒果） [英] Poor UDP performance with Windows Phone 7.1 (Mango)

问题描述

我试着去不断地从三星Omnia 7的Windows Phone 7.1的Beta2刷新（芒果）送小UDP的数据包（8字节）尽可能快地以一个标准的PC与Windows 7和我非常不稳定的表现。

Im trying to continuously send small UDP-packets (8 byte) as fast as possible from a Samsung Omnia 7 with Windows Phone 7.1 Beta2 refresh (Mango) to a standard PC with Windows 7 and I get very erratic performance.

最奇怪的是每1-4个左右毫秒发送一条消息时，我得到了最好的性能。如果我更快地发送消息（小于1毫秒）的或的速度较慢（> 4毫秒），我得到了奇怪的寒冻，其中包似乎卡住（0.5-1秒，每隔约0.5秒）的地方，才得到一阵再次释放。

The weirdest thing is that I get the best performance when sending one message per around 1-4 milliseconds. If I send messages faster (< 1 ms) or slower (> 4 ms) I get strange freezings where the packages seem to get stuck (for 0.5-1 sec every ~0.5 sec) somewhere before they get released again in a burst.

另一个奇怪的现象是，发送手机应用程式似乎仍在不断地发送消息。这是因为如果在寒冻出现的应用程序之外，也许在手机上的网络设备（+）。但是，为什么是最佳的信息之间的1-4毫秒的延迟？为什么与发送邮件时，我得到更多的这些寒冻的下的速度（5-50毫秒）？

Another weird observation is that the sending phone-app still seem to send the messages continuously. It is as if the freezings arise outside the app, perhaps in the network-device on the phone (?). But why is a 1-4 ms delay between the messages optimal? Why do I get more of these freezings when sending messages with a lower rate (5-50 ms)?

（当从仿真器发送我得到良好的性能。）

(When sending from the emulator I get good performance.)

更新

林种给这个了现在。也许它工作在WP7.1的最终版本更好。他谁等待将要看到的。

Im kind of giving this up for now. Perhaps it works better in the final release of WP7.1. He who waits shall see.

推荐答案

似乎有一个问题，WP7上发送的UDP数据。看到这个MS连接问题日志

There appears to be an issue with sending UDP data on WP7. See this MS Connect issue log
