  Hi,
  
  Please find the initialization code. I have seen your example code on scroller. My requirement is similar to that I would be able to display large number of records(50,000) at a time. But with 2000 records itself ie not responding. Also the memory grows higher Ex 30MB. Can you plz help us whether the setting is correct.

  oTable = $('#sTable')
  .dataTable(

  What part of it is slow - I'm going to guess the "testAction.do" script. If that's the case, then it is outside the scope of DataTables since that's not a script provided as part of the project. As I say, server-side processing, when implemented correctly, should be able to cope with millions of rows no problem. I don't know what your implementation looks like, but personally, I would start by looking at that.

  Hi,
  
  Thanks for your response. testAction.do is going to fetch the rows from DB and returns as JSON array. Fetching part is quite fast. But rendering part taking long time. If I leave the browser like that the ie will not respond at all. What could be the reason for increase in the IE memory.
  
  Also, during scrolling, the table not make ajax query for additional data-loading like this scroller example: http://datatables.net/release-datatables/extras/Scroller/server-side_processing.html
  
  
  Thanks

  I need a link to a test page showing the problem to have any idea of what is going on.
