What I really want to know is: Given that I used to do one updates of size n, and now I can do k updates of size m (n=k*m) in the same time, I can essentially do k times as many updates. What is k? "By replacing a batch-based indexing system with an indexing system based on incremental processing using Percolator, we process the same number of documents per day, while reducing the average age of documents in Google search results by 50%." This statistic, about a 50% reduction, is difficult to interpret. It is hard to understand what sort of improvement on would see on other measures, like the one I proposed above.
