Tips for improving grid performance

[assaf.frank123Participant]

Hi,

I have a grid with about 30 columns and may get to about 2000 rows.
The grid has filters (showfilterrow:true),sorting,several aggregates and some cellrendereres.
Before reducing this functionality how bout the way the grid is populated:
Today I populate with local javascript array.

Will using JSON improve the performance (when talking about 2000 rows)?
Any other ideas?

Thanks

Hi assaf.frank123,

Things which affect the performance are the features you turn on. showfilterrow requires creating a Filter widget for all your columns which is more time consuming than creating a Filter Menu for all columns. Custom cellsrenderer implementations override the Grid’s built-in rendering logic and depending on the code you write there, your performance will be affected.

1. How about passing the data by JSON from the server? Can this improve the loading time?
2. Are you aware of any browser caching issue – perhaps getting too large?. We notice that on some desktops loading screens are very slow while on others
it goes much faster. Both desktops are strong i5 machines. We noticed that after restarting the problematic computer the situation improves for a
little but gets worse again very quickly. We are working with chrome browser.

Thanks

Hi assaf.frank123,

1. No. this does not matter.
2. Browsers usually cache web pages and the PC speed is important how fast the browser performs, too.
