I am trying to ResolvePrincipal using People.asmx in two seprate farms. Both farms are single server farms with same configuration . Both farms target the same AD for user information. End point of AD being use din both the farms are the same .
But one one server it takes average 3.5 seconds to Run this web service method, but on the other it takes 43 seconds.
What could be the reason behind ?
