AS/JS Virtual Machine Performance Race

This summer, I'm luckily interning at Adobe working on Tamarin. Since I haven't touched Tamarin in a while, I thought it should be worthwhile to see how Tamarin compares to all the other JavaScript virtual machines. Although Tamarin isn't a JavaScript VM, there aren't any other ActionScript VMs to compare it to. Without further adieu, the SunSpider benchmark contenders:

• Tamarin-Central: Stable Flash VM. Runs ActionScript
• Tamarin-Redux: The tip for Tamarin-Central. Every once in a while the Tamarin-Redux changes are pushed into the Tamarin-Central branch
• TraceMonkey: Tracing JIT slated for shipment in Firefox 3.1
• V8: Used by Google Chrome
• Nitro: Previously named SquirrelFish Extreme, the VM in Safari.

A few notes:

• Tamarin-Central/Redux AS3 - SunSpider tests written with static typing. Only available for Flash VMs.
• All VMs are from their respective repositories and checked out 3/22/09 ~6 PM PST. Built with optimizations/release builds.
  
• All tests run on a MacBook Pro 2.4 Ghz w/ 4 Gigs of ram.
• These tests run really really fast (some less than three ms)
• The baseline is the Tamarin-Central interpreter (JIT disabled)
• Some SunSpider tests are omitted as Tamarin can't run them because of known issues.
  
• Take these numbers with a grain of salt :)

I'd like to see the results in a large image as well :). we can't really read it as the linked image is the same size as the preview one :(

Thanks!

Hmm didn't realize that the image was so small. I actually don't have the graph anymore. The results are over a year old and probably don't mean anything anymore. Sorry :(
