+    This compiler is used when code is changed within the running IDE or application,
+    and when source code is loaded.
+    It generates bytecode methods, which are (typically) further translated to machine code by the VM,
+    when first executed 
+    (although for some architectures, no JITTER is available, and the bytecode will be interpreted, 
+     which is of course much slower).

+    This is not to be confused with the stc-compiler, which generates plain machine code, 
+    which is packaged into compiled class libraries and runs with very good performance. 
+    Usually, end user applications are deployed as stc-compiled binary code. 
+    And only patches or dynamically generated code uses bytecode methods.
+    Therefore, the speed of the bytecode interpreter is usually not at all relevant to a deployed app's 
+    overall speed (and also not to the ST/X IDE itself, as it also consists of precompiled machine code).
