ListGrid performance issue for big number of rows

Hello,

We have listGrid together with restDataSource. RestDatasource has 27 000 000 total number of records and returns 150 records per request.
To render a first result for Chrome 39 takes ~6-7 seconds. To select a row ~4 seconds.
For Firefox 32: ~2-3 seconds to render a first result and ~10 seconds to select a row
IE 11 can't even to render properly a first page.

So question: How to increase a performance of ListGrid? Or does ListGrid have a limit how many rows to display?

P.S. we use smartgwt 5.0p
