=== Results ===
+
+ ==== CPU and wall clock time ====
+
+ These results were obtained using a byte code instrumentation tool.
+ The CPU times include both system and user CPU.
+ The runs were done on a Solaris 10 machine with x86 hardware. Wall clock time
+ were obtained using ''gethrtime'' and the CPU times using ''getrusage''. [[BR]]
+ The test client was run with Java SE 6 (build 103), 35 seconds of warmup and 120 seconds runtime ("steady state").
