   @gengliangwang 
   QQ regarding the regression test:
   
   > the difference for LevelDB is
   > before changes: 2.5s
   > after changes: 3s
   
   How many stages within your test log file for SHS? Or will this performance regression get amplified if there are more stages within the application?
