To view the discussion, visit: https://community.jboss.org/message/801789#801789 -------------------------------------------------------------- Hi All, My setup is: JBOSS AS 7.1.1 and PostGreSql When there are no or very less (a couple of hundred) records in the table, my inserts/updates completes very fast. But when the number of records get to a couple of thousand, the inserts or updates take an extremely long time. For ex: inserting a record takes more than 1 or 2 seconds. Not sure where the problem is or where to start. My code to update the database looks like this - public long updateRecord(long id, List<MyData> myDataList) {        Event eventFromDB = findById(id).get(0); for(MyData myData : myDataList) {                                         eventFromDB.getMyData().add(myData);                          } em.merge(eventFromDB); return 1L;           } I am a newbie and have set up the jboss as to the best of my knowledge. I haven't done any configuration settings on either the JBOSS AS or the PostGreSQL. The JBOSS AS is running in the standalone mode using the standalone-full.xml config file. Thanks in advance. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/801789#801789] Start a new discussion in Beginner's Corner at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
