IIs there any information about how Graal+FastR are right now with respect to memory usage and warmup speeds? Are these benchmarks for total wall time or just the post-warmup speed?
However, it is true that the warm-up and memory usage are something we need to improve. We're working on providing native image [1] of FastR. With that, both the warm-up and memory usage shold get close to GNU-R.
