If you are loading large numbers of records also make sure that you are
setting the size of the IOC's hash-table before dbLoadDatabase() or
dbLoadRecords() in your startup script. The size argument must be a
power of 2 up to 64K:
dbPvdTableSize(65536)
The default size is 512, although we should probably increase that
nowadays. More hash buckets means more efficient name searches both at
load-time and by the CA name resolution task.
