I used to have a similar problem at http://zunzun.com, where a large data set would take a lo-o-o-o-ong time to surface fit using nonlinear methods. Originally I served requests serially as well, so everyone using the site had to wait until the larger data sets completed. I solved the problem by multithreading my application using WebKit's threads. Multiple users can have their requests served simultaneously, and I have a status page refreshing every two seconds using another servlet that checks the long-running thread's progress. To see this in action try running the function finders on my site.
