David,
The rendering of this grid takes over 20 seconds on a 20 (rows) and 30 columns. Yes we have a custom cell renderer which has two images and 3 labels. We have disabled live scrolling, however as indicated it takes approx 20 seconds to render this grid. I suspect that it will take considerably longer on a client machine. Any guidance would be appreciated.
