Thanks for the info Simon. As far as the users waiting goes, thats easy... They will wait as long as I tell them to as long as I give them something to look at and a reason (Spinning CD and a "Please wait, Reticulating Splines" message perhaps). In fact the entire process isnt really a vital part of the program, it is simply to display some extra information for other users who may want to download it. So if that information was updated say 5 minutes later, it wouldnt really matter. In any event, I am having a look at starling and working to start a threaded process in the background and update the record whenever it finishes. If however libxml is as fast as you say, perhaps I simply need to do some load balancing and make them wait. Of course a major problem is that I still dont know where to call the processor from. Rails can be extremely frustrating when you are still learning it.
