Opera Javascript Comparison

Since I've been posting about javascript performance lately I thougt I would compare Opera v.9.52 JS performance to the current release of Xulrunner running under Epiphany 2.22. The results are mixed. Celtic Kane's javascript speed test shows results that best Gecko but not Webkit.



In comparison I was only able to achieve a score of 255 (lower is better) for the current Xulrunner. This looks good for Opera. Let's take a look at the sunspider benchmark now. Xulrunner is show in the FROM column while Opera is shown in the TO column.



As you can see Opera's javascript perfomance is significantly slower than Xulrunner's performance. I am a bit confused by the results considering Opera did pretty well in Celtic Kane's test and I have heard that Opera's JS performance is very good. My sunspider results were so out of whack from what I was expecting that I ran them again but the results were the same. I wonder if anyone else can confirm my findings.
