On the Nexus 7 there\u2019s once again the same image: Java is 106% slower than C, Javascript only 43%. Amazing.<\/strong> For simple numeric benchmarks the performance of Javascript is simply astonishing. On the MacBook Pro Javascript is incredibly close to the performance of C and Java. On the iPhone Javascript was within a range of factor 2.1. For me it was very surprising to see V8 on Android being able to beat Java on the Davlik VM by a large margin.Fine print: Slower and faster usually cause headaches in benchmarks (There a nice paper about that http:\/\/hal.inria.fr\/docs\/00\/73\/92\/37\/PDF\/percentfaster-techreport.pdf). I sticked with the elapsed time, such that e.g. 42% slower means that the factor of the durations was 1.42. On the MacBook Pro C was compiled with clang using -O3 -fomit-frame-pointer -march=native -mfpmath=sse -msse3 for x64. Java was Oracle Hotspot 1.8.0-ea-b87 on 64 bit (thus C2 aka Server Hotspot). Chrome was 28.0.1493.0, but the 32 bit version. I tried to compile V8 myself, but both the x86 and x64 custom built V8 were significantly slower than Chrome so I stick with Chrome. On the iPhone I used a release configuration using clang with (among others) -O3 -arch armv7 The Google Nexus 7 runs Android 4.2.2, Chrome 26.0.1410.58. C was compiled with -march=armv6 -marm -mfloat-abi=softfp -mfpu=vfp -O3.<\/p><\/blockquote>\n
