We have a customer that  is using Laserfiche Connector v10.  It is installed on the third party application server.  There are four of these app servers that the end users use to access the third party software.  When they are performing task using Connector, it will often push the CPU usage for lfc.exe to almost 50% and then release when finished.  Is this normal?  The Connector is only performing a field search in the LF repository.  Has anyone else had this issue?  If so, how did resolve it?
