I'm in a confusing situation right now: I have 2 MS Server 2008, hosting a WCF-Webservice which is basically reading data from an SQL-Server and forwarding it to the client.
We use NLB to loadbalance those two applicationservers.
During Loadtests there is now a strange reading in the performance-logs: the CPU and MEM Load is quite even throughout those server, but only one server is building up write-queues on the HD, the other isn't.
Is there any relation between those readings and the NLB?
(The servers are only hosting this application: nothing else and are configured the same way)
