FWIIW, this is the kind of ratios we get on our (slightly modified) 
SPECjvm2008 runs, Github Graal vs OpenJDK vs Oracle JDK (baseline), all 
1.8.0, builds from around end of year:

---                 Github Graal    OpenJDK
compress             0.9511590     0.9883032
crypto.aes           1.3176631     0.9793367
crypto.rsa           4.1464020     0.9600780
crypto.signverify    1.3656185     1.1123288
derby                1.2369832     0.9961086
mpegaudio            1.2829063     1.0164686
scimark.fft.large    0.9846439     1.0307498
scimark.lu.large     1.9127555     1.0249192
scimark.monte_carlo  2.2114020     1.0217201
scimark.sor.large    1.2000043     1.0155251
scimark.sparse.large 1.6860926     1.0442726
serial               1.0336566     1.0413808
sunflow              0.8692992     0.9902927
xml.transform        0.8981167     1.1286714
xml.validation       0.9969519     0.9885531

I wouldn't take the crypto benchmarks at face value without checking 
that all platforms involved use the same security provider.
