Slow speed when searching proxy settings

Hi,

I am trying to call a web service in Matlab using the callSoapService function. However, I find it is very slow. After checking the codes, I find that

proxy = com.mathworks.webproxy.WebproxyFactory.findProxyForURL(url);

this line costs the most time. However, I am quite sure that I don't need proxy in this call. Is there any way to get rid of this annoying check?

Thanks!
