Symptom:
The PCG UI on the ISDS Administrative Console is slow.  After selecting a PCG and clicking Edit, 45+ seconds pass before the Update PCG window appears.  This is observed on a VZ production system replicated in the SIT lab.  This system has 31 PCGs defined in the database.  The slowness appears to be limited to the edit function described above.  The save and cancel functions execute within an acceptable time period.

Conditions:
It appears that the time required to open the Update PCG window is longer on systems with more PCGs.
