Check out http://arewefastyet.com/ (the website mentioned in the article), which tracks javascript engine performance. Spidermonkey is faster than v8 and Safari's JSC on all three popular javascript benchmarks [1]

[1] Octane (google's benchmark), Sunspider (Apple/Webkit's benchmark), and Kraken (Mozilla's benchmark).

Is there a reason they don't have the new Safari 8 FTLJIT in those numbers? JSC (Java Script Core?) was Safari 7 wasn't it?

According to [1]: "Last week I asked for benchmarks of the new JavascriptCore Fourth Tier LLVM JIT. Arewefastyet from Mozilla now includes such results. FTLJIT does particularly well on asm.js examples."

You can see JSC performing better than chrome on the asm.js benchmarks: http://arewefastyet.com/#machine=12&view=breakdown&suite=asm...

FTL is shown there, but note that FTL only works on 64-bit machines. Click on "machines->mac os x 64-bit" to see the results. They are indeed much better than without FTL.
