           Summary: Performance bottle neck in Digir ProviderServlet
           Product: SEEK
           Version: unspecified
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: major
          Priority: P1
         Component: ecogrid
        AssignedTo: kruland at ku.edu
        ReportedBy: kruland at ku.edu

Now that each digir ecogrid query requests information from many different
providers (400 or so at any time), the performance of the Digir ProviderServlet
is a problem.  In addition to the additional network hop between the ecogrid
DigirImpl and the Digir ProviderServlet, there are configuration issues in the
ProviderServlet itself.

A stopgap measure is to throttle back the Ecogrid DigirImpl service to accepting
a reduced number of simultaneous connections.
