Invoking Business Rules Remotley performance issue

Hi Guru’s,

We have created some set of policies in BRE to validate incomming data in the Business layer and those are having forward chaining also. created one rule engine facade(wcf service hosted in IIS ) to intract remotley.

this is working fine in local server but making performance issue when running in virtual machine. This issue is only when first time hitting the service second time onwards it is working fine.

here is the flow

Business layer->Consumed Rule Engine Facade service hosted in Biztalk Server IIS->Executing the rules and return the result output.

Can someone suggest where might be the reason? Please tell me is any input required.
