AmazonIdentityManagementServiceClient is too much time consuming

I am initializing Amazon client from a web-api. The following code is almost taking over 1 min.

Amazon.IdentityManagement.AmazonIdentityManagementServiceClient client = new Amazon.IdentityManagement.AmazonIdentityManagementServiceClient(cred);

Solution

I checked this issue reproduce only when I run AWS services from my local source code in debug mode, while compiled and production environment it is better.
