@@ -9,6 +9,14 @@ To achieve this, we use a sample program ("test-instr.c") where each path is
 equally likely, supply it a single seed, and tell AFL to exit after one run of
 deterministic mutations against that seed.
 
+**Note that this is not a real-world scenario!**
+Because the target does basically nothing this is rather a stress test on
+Kernel I/O / context switching.
+For this reason you will not see a difference if you run the multicore test
+with 20 or 40 threads - or even see the performance decline the more threads
+(`-f` parameter) you use. In a real-world scenario you can expect to gain
+exec/s until 40-60 threads (if you have that many available on your CPU).

 Usage example:
