Hi Vasya,

Okay sounds great I have attached a zip with both my html page and a js file that has a sample data set with 25,000 rows. when I open this html page with chrome and have the virtualization code in I get an average of 11.62s for rendering. When I have the virtualization code commented out I get an average of 8.86s for rendering. I should also mention the amount of data could potentially be 100,000 rows x 100 columns so it would have to be fast for a data set that size also but I was just working at 25,000 rows as a starting point.

Thanks,
Kelsey 

Hello Vasya,

So paging is not an option. I am researching different tables I could use for a trading application for Citi bank and we need all the data in 1 scrollable page. I read about the virtualization and it seemed like it would work. I added the lines

rowvirtualization: true,
virtualizationMode: "continuous",
height: "100%",
width: "100%",

to my grid however it didn't improve the performance. Actually I timed it using google chrome and the rendering time got longer by about a second with the virtualization. Perhaps I am adding the virtualization in wrong or if not maybe you have some other ideas about how I might improve the tables rendering speed. 

Thanks,

Kelsey
