Dear Mr. Peter,

For 4 months, we have used your product for our renewal project to extend “Open Market Seller Office web application” to Cross Browser and Mobile.
However, now we are in trouble with applying jqwidget grid in your product. If we apply it, we meet a big problem with the speed of grid.

You jqwidget grid has a critical problem with rendering performance.
There are more than 30 grid column. If we apply the renderings to all those columns, we can see the performances in all web and mobile browsers become very slower.

If we just check the performance only with your product, that problem seems to occur only when we use IE.
IE(8,9,10,11), Chrome, Safari, Firefox
Android, IOS

The target of our project is to extend the function to Cross Browser and Multi Devices.
We got a feedback from our customer who asked us to fulfill this project. After their quality test division tested our result of the project, they decided that the availability of our result of project for various devices is good but the quality of performance is low.

If we compare our product with other products, our product’s performance is slower than Ext-JS, JQ-Grid, FlexGrid(IE-Only). In my opinion, this is because of the difference of Rendering Style.

For example,
1. When move from mobile to web scroll, the movement is not so smooth.
2. Loading for the first time, if we use ‘cellrenderer’ in column, the change of scene is not smooth.

Opinion)
1. The part of Column Rendering in Grid is too heavy.
2. Each every time Mouse or Data is changed, there would be various event calls.

Even though, except those, still there are many other opinions for your product,
Now I get too much stress because of the speed of performance.

Isn’t there any proper way to optimize your product?

PS :
Your API Document just guide us with small range without regard to the real cases of work.
To find a real cases to apply for this project is not so easy.

It would be much better for you to raise the price and give better service.
I am quite sure that jqwidget can succeed if jqwidget more service minded globally.

Thanks and Regards,
HanGyu Kim in Seoul, Korea
