However, if I press and hold say C-n, the cursor will move down line by line perhaps 10-30 or so times but then freeze for a while and finally reappear whenever I take my hands off the keyboard or at the bottom of the buffer if I don't release the key.
Thanks for the details.
It indeed sounds like Exceed is an important factor here.

Does the problem happen for you when you run Emacs locally on that
machine? Or does it only happen in this particular configuration,
when you use Exceed to access a Solaris server from a Windows machine?

Comparisons with gvim are meaningless, because there's no primitive
"highlight this text" operation that both Emacs and gvim use. Each
one of them highlights text using very different methods. In Emacs,
the portion of the text that is highlighted is actually fully
redisplayed.

When I log in to the Solaris server through a PuTTY client, I do not experience the problem. The problem does occur within the Exceed X terminal window if I start Emacs with the -nw option.
