Oracle claims that its graalvm implementaion of R (called "FastR") is up to 40x faster than normal R (https://www.graalvm.org/r/). However, I ran this super simple (but realistic) 4 line test program and not only was GraalVM/FastR not 40x faster,…

Does GraalVM use same thread and heap space when calling polyglot functions?
If I call R code from Java within GraalVM (using GraalVM's polyglot function), does the R code and the Java code run on the same Java thread (ie there's no switching between OS or Java threads etc?) Also, is it the same "memory/heap" space? That is,…
