Is each field in a separate panel? Are there more than 50 panels on the

I put 100 JTextFields each in it's own panel, plus some more panels and
containers for formatting, and I don't see any slowness. You might, and
maybe your needs are more sensitive than what I did, but this seems to
update fine for me.
