How to improve scrolling in a SWT table [message #1452138]

Hello,
I am playing with a Table example "TableColumnListenerFactory" found on java2s ( you can google the link for it )

It does a good job in illustrating sorting, and in it scrolling rows back and forth is really fast.

I noticed by adding a simple checkbox button column, it results in extremely slow scrolling. What make scrolling so slow? And any ideas/pointers to help?

Even when using virtual table, it is just as bad when the entire table is loaded. With Virtual table as long as the TableItems are less, it scrolls fast and as more items get added, scrolling gets worse.

I have attached modified source code to show bad scrolling behavior.

Any help, appreciated. Thanks
