View Full Version : performance problem: grouping grid

18 Dec 2009, 9:12 AM
hi all,

we have a grouping grid in our application - like the example in the explorer demo.

the difference to the demo:
- we load the data after building the grid with "store.add(List of Models)"
- about 300 rows with about 10 columns for 1 row (many groups - about 20)

i can see on the server-side, the data is loading very qick from our database. but
after loading from the database, it takes a lot of time i can see the result in the grid.

i tried the same grid and amount of data with NO GROUPING --> very fast and no delay.

so me questions are:
- can i prepare the data on the server-side in a way, the groupinig is faster
on the client-side?
- or any idea, what could be wrong with my code?

thx for helping

Groupinggrid cannot handle big amounts of data very fast. We are looking into changing how GroupingView works for GXT3 to make it faster.

so there is nothing i can do?
for example ordering the data on the server-side, so the client only has to show the result?

what is so time consuming?
