One way would be to set the unit increment of the scrollbar to a larger number:

scrollPane.getVerticalScrollBar().setUnitIncrement(20);

I was trying to find a better method to read through 32000 lines in my ScrollPane

try this

scrollPane.getVerticalScrollBar().setUnitIncrement(100); scrollPane.getViewport().putClientProperty("EnableWindowBlit", Boolean.TRUE); scrollPane.getViewport().setScrollMode(JViewport.BACKINGSTORE_SCROLL_MODE);
