I am using a dedicated server and same subnet on my development computer, So I think this is not network and hardware issues.

It's too slow when loading the thousands of products and I have a million of customer records.

Seems that it's javascript issue that load all data first from  server  to the browser

and put it in a container using backbone.

Any solutions to those  already implemented openerp that migrates million of records that had the same problem encountered?
