使用NSURLConnection缓慢下载

Question

我正在执行一个请求（SOAP webservice）并且响应速度非常慢（请参阅下面的日志）。

这个问题既发生在设备上，也发生在模拟器中。
当我使用cURL或SoapUI执行相同的请求时，但是呼叫一秒钟内完成。
什么可能导致这种情况？

代码

NSString *msgLength = [NSString stringWithFormat:@"%d", [soapRequest length]]; 

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];    
[request addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];  
[request addValue:msgLength forHTTPHeaderField:@"Content-Length"]; 
[request setHTTPMethod:@"POST"];  
[request setHTTPBody:[soapRequest dataUsingEncoding:NSUTF8StringEncoding]]; 
connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

我不能回答你的问题直接。也许它与你的代理处理程序有关？也许可以帮助发布这些。

无论如何，我真的想把ASIHTTPRequest引起您的注意。这是一个广泛使用和流行的选择，可能会让你的生活更轻松。
