Why is this code so slow? (vCloud .NET API)

I apologize a thousand times but I couldn't find code tags. Anyway, why is this code so slow? There are about 70 total machines deployed and this takes between 30 seconds and a minute to run. Have I done something terribly wrong? I also apologize if this is not the correct vCloud community for this question.

            var client = new vCloudClient(url, com.vmware.vcloud.sdk.constants.Version.V5_1);

            client.Login(user, pass);

            Organization org = Organization.GetOrganizationByReference(client, client.GetOrgRefByName("MyOrg"));

            ReferenceType reference = org.GetVdcRefByName("MyVDC");

            Vdc vdc = Vdc.GetVdcByReference(client, reference);

            IEnumerable<KeyValuePair<string, Vapp>> apps =

                vdc.GetVappRefs().Select(x => Vapp.GetVappByReference(client, x))

                    .Select(

                        x =>

                        new KeyValuePair<string, Vapp>(User.GetUserByReference(client, x.GetOwner()).Reference.name, x))

                    .Where(x => x.Key.Equals(username));

            Console.WriteLine("{0}: {1}", username, apps.Count());

            Console.WriteLine("Deployed: {0}\nUndeployed: {1}", apps.Count(x => x.Value.IsDeployed()), apps.Count(x => !x.Value.IsDeployed()));
