[WM] Using ws on WM seems to have performance issues (Welcome to discuss)

Would like Program Using WS, but it has never been practiced. Today I wrote a small demo to see how the WS performance is. The server is not written by me, and I use a public server:
1. Random Number
Http://www.webxml.com.cn/WebServices/RandomFontsWebService.asmx
2. Weather
Http://www.webxml.com.cn/WebServices/WeatherWebService.asmx
3. Search
Http://api.search.live.net: 80/soap. asmx

In the weather, only the weather in Shanghai is fixed, and several keywords are provided for the search. The search results are printed on the console (although the Console does not respond on WM ).
In other words, we use the profile tool to test on the real machine. The machine Hisense E8 and the network CDMA 1X (which should be, maybe evdo, I cannot tell ).
The result is as follows:

The random number needs 1.4 S, and the weather needs 1.7 S. Bing's search actually needs 11 s ......

I don't know if other talents have used WebServices on WM (including wince? Is your application performance so poor ??

How do you solve these problems?

Welcome to the discussion.

PS:

As shown in another figure, the test above should be problematic. 20 keywords are searched and the results are searched 7 times. An exception occurred in the middle and the results are broken.

Result:

 

 

The results of this time tend to be normal. In the real network environment, it takes about two seconds to access ws. Do I think this time sometimes takes a little longer ??

I don't know what you think about this problem?

Welcome to the discussion.

PS:

After some tests, it is not very accurate to conclude that the performance of WS is not very poor... maybe XML is really heavyweight...
