Here's a related question:  Do any of the mentioned R-web interfaces
(Rweb, R-Online, CGIwithR, RSPerl) support reusing the same R process,
eliminating the startup overhead?  This would be useful to me as well.

Currently I use such a method on my computing cluster: All 40
compute nodes run an R process/compute server that listens at a socket for
any
connection and subsequent commands from another computer.
When the master process disconnects, the R processes go back to listening
at the socket. Connecting to the R compute servers this way
takes < 2 milliseconds rather than the typical ~2 second R startup time.




I only know about CGIwithR, which is very simple and starts a new R for every request. Startup time on my Mac is around 1.3 seconds; for my own purposes this is absolutely fine, but I can appreciate that it could well be problematic in certain kinds of application (eg where a very large amount of data has to be loaded).


Best wishes,
David
