My experience with Java applets (appletviewer, Netscape 2.0, HotJava) is
that they "execute" at an unacceptably slow rate on a Windows 95 machine with
8 megs of RAM. Simple applets, such as Tic-Tac-Toe or other graphics-only
applets perform well, but introduce user-interface controls like Button,
TextField, etc. and there is a significant delay before anything appears
on the screen while the interpreter interprets.

Is interpreter speed the most important performance factor? Could the
applet viewer (be it Netscape, HotJava, or other) be slowing things down?

I Agree. Will it be enough, though, to satisfy the performance requirements
of the average real-world application?
