changchichung opened a new issue #7204: how to improvee the rendering speed
URL: https://github.com/apache/incubator-superset/issues/7204
 
 
   ### Superset version
   0.28.1
   
   ### Expected results
   quick / page table
   
   ### Actual results
   long time rendering , all rows in one page.
   
   ### Steps to reproduce
   
   I wrote a query which return about 93k rows . in psql console , that query only takes few seconds to return the result.
   but in superset , with different browsers , the rendering take long time from 2:24(chrome) to 3:38(firefox), and take high single core CPU loading
   
   here is the screen recording 
   firefox: https://www.youtube.com/watch?v=s_SH8U67_Dg
   Braver(chrome): https://www.youtube.com/watch?v=X1WUxNrF_YA
   
   OS: Ubuntu 18.04.2 LTS
   CPU: i7-2600@3.4G
   RAM: 8G
   H.D.D: Pleextor M6P 128G SSD
   
   is there anyway to improve the rendering speed ? 
   maybe take 1K rows or 100 rows per page ?
   
   I search the issues and there`s a topic talk about "limit button" in superset , but I dont see that button in my page , how to enable the limit option ?
