Hi,

I just compiled SpiderMonkey 1.8.5 and V8 into the same app to simulate behaviour of a VXML browser. The purpose was to see if it was worth switching from V8 to SpiderMonkey on the JavaScript cluster we use for VXML/CCXML. The idea was that we maybe could upgrade FS and re-use this work in FS rather than going through the pain of maintaining a separate JavaScript engine.

SpiderMonkey 1-8-5 execute one of the test scripts ca 4000 times per second. V8 managed 60,000 executions per second on the same script.

It’s a arger difference than I expected based on some of the benchmarks I have seen, but well speed alone is not everything. V8 do not support Sparc L etc.
