RScheme is freely redistributable, and offers reasonable +performance despite being extraordinarily portable. RScheme can be +compiled to C, and the C can then compiled with a normal C compiler to +generate machine code. This can be done from a running system, and +the resulting object code can be dynamically linked into RScheme as a +program executes. By default, however, RScheme compiles to bytecodes +which are interpreted by a (runtime) virtual machine. This ensures +that compilation is fast and keeps code size down. In general, we +recommend using the (default) bytecode code generation system, and +only compiling your time-critical code to machine code. This allows a +nice adjustment of space/time tradeoffs. + +To the casual user, RScheme appears to be an interpreter. You +can type RScheme code at a read-eval-print loop, and it executes the +code and prints the result. In reality, every expression you type to +the read-eval-print-loop is compiled and the resulting code is executed. |
