Spark can't display roster

I use Spark 2.5.7 + openfire 3.4.1+ mysql database. When I add contacts and groups over some amount, display none in the spark window. Mybe because I add too many rosters. In my database(openfire), record number of table jiveRoster and jiveRosterGroups is over 150,000. Meantime , I find relay time is 5 seconds when smack.jar read rosters. I try to enlarge it ,but nothing happen. where should I modify?

How many rosters are supported by Spark? or How can I let all rosters display correctly.?
