Hi

I am creating a more than 100 columns in nebula grid using for loop, Its working fine in windows platform, but when the same source is run on ubuntu linux it will take time to load. In Ubuntu it will take more than 10secs and in windows it will take only 2-3 seconds. Please help to resolve this nebula grid columns creation loading time issue in ubuntu linux.

Manoj,

Have you measured anything with a profiler yet? Could you characterize
what type of hardware you're running in each of the cases?

Hi Ed Merks,

Thanks for the response. On both Windows XP and Ubuntu Linux we are using strong (good) hardware.

The code is as follows :

for (int i = 0; i < 200 ; i++)
{
GridColumn column = new GridColumn(bottomGridDayView,SWT.NONE);
if(i==0)
{
column.setWidth(20);
}
else if(i==1)
{
column.setWidth(30);
}
else if(i == delimitCol)
{
column.setWidth(5);
}
else
{
column.setWidth(3);
}
}

We are creating around 200 columns on the grid (bottomGridDayView). The grid is formed by the code below.

bottomGridDayView = new Grid(canvas,SWT.NONE | SWT.V_SCROLL | SWT.H_SCROLL);

bottomGridDayView.setHeaderVisible(false);
bottomGridDayView.setRowHeaderVisible(false);
bottomGridDayView.setCellSelectionEnabled(true);

On Windows XP :- Above code loads the grid in 2-3 seconds
On Suse Linux :- Above code loads the grid in 2-3 seconds
On Ubuntu Linux :- Above code loads the grid in more than 7 seconds

We are facing this problem only on Ubuntu linux operating system.

Please help us to solve the issue.

Regards,
Manoj
