Hi, I am not sure about your data structure, but if you do not alter those often from third-party programs, then storing the information in R's native file formats (like RData) might give you some performance boost against always querying MySQL. Of course this depends on data structure and volume. Also, checking out some NoSQL techniques (like CouchDB or redis) might be a good idea for a web service - if your data is not profiting from relational database structure. Well, you need some benchmarks here. About plots: I would not say that the base graphics library (or even lattice) would be slow, although ggplot2 has some issues. So IMHO it depends on what type of plots would you generate, but I would say there would be no serious performance issues. After all: I think going the direct R way is great option :)
