Insert commands trigger parsing
--------------------------------

          Key: HHH-5527
          URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5527
        Project: Hibernate Core
      Issue Type: Improvement
  Affects Versions: 3.2.6
     Environment: Solaris 10 update 8, Oracle 11.0.2
       Reporter: Mahendra M Gharpuray
       Priority: Critical


While running several thousand concurrent inserts, we noticed a huge amount of parsing. Upon detailed investigation, we found that the parsing was for select * queries tied to the table into which inserts were happening. For each insert, there was a select * call and that was parsed each time. This resulted in poor performance of the application. Parsing was consuming 99% of database time leaving only 1% time for actual query execution.
