Interesting. In any case, I didn't realize that looking at our queues is a great place to consider parallelization.

I am guessing that you would be against a "performance" tab in LyX? For example, "Performance" is one of the 6 preference categories of Okular. The option within there I like the most is "Memory Usage". I can set it to "Greedy" and then zoom in far to PDF and still be able to scroll. I like having that control. But I understand that we want to be careful before adding more preferences. Scott
