Chris,
You have two choices:
Lighten the load on the server.
OR
Get a better machine.
One simple method to determine load on the Win box is Task Manager. This will give you a feel for processor consumption and memory size.
If the only loads are mysql and Tomcat then you are forced to consider you application or hardware. I had an issue in my app that when the requests rose to a certain level the load went exponential due to people reclicking. I ended up caching one of my main pages and only updating it once a minute. This reduced the Tomcat load and the mysql load. It however increased the memory footprint of my app. So if you can hold some information in memory and not request it every time you can decrease the load on mysql. Down side is that you will need more memory (maybe?). A profiler should be your next venture. As stated this is a fairly small box, but it is only an issue if all else is optimal.
As for would upgrading the machine fix your problem, only you can answer that. It will help and will be able to serve a lot more request but may be a total waste of money if the real problem is in your app. If the issue is a memory leak it may make very little difference. Same goes for adding a second box for mysql.
All this takes us back to the root of the issue. Why is it slow? Is the motor too small (has a 1.8 liter, needs a 4.2). Is there too much load (8 people in a four passenger car). Or is the app sloppy(Only 2 people but caring a ton of luggage. You know packs everything just in case.) rather than sleek and efficient. What if none of these are it? You could have a bad sparkplug (something wrong in the system).
Every design has trade offs and the environment should guide you as which direction to work in.
Nobody knows your needs as good as your and thus no one on the list knows all the details that go into you situation. And that is why you get the general answers rather than a definitive yes or no.

Would this problem be solved by a hardware upgrade?
