PERFORMANCE PROBLEM DURING BACKUP WHEN ANTI VIRUS SOFTWARE IS
ACTIVE
STAT= CLOSED  PER  FESN0907344-     CTID= SJ0291 ISEV= 2
ERROR DESCRIPTION:
Customer reports a performance problem when backing up a
filespace where AV software is active. A trace with
INSTR_CLIENT_DETAIL for filesystem with AV inactive shows:
Process Dirs        0.485          242.5              2
this value compares to the following reported when AV active:
Process Dirs        0.844          422.0              2

(sample values from this customer only, you will see
significantly higher Process Dirs value compared to AV off)
