(Core :: JavaScript Engine, defect)

Description

Attachment: sunspider results.txt

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:19.0) Gecko/19.0 Firefox/19.0
Build ID: 20121112030753

Steps to reproduce:

I did a series of repeated benchmark tests using sunspider-0.9.1 without closing the browser between each test.


Actual results:

The browser took an increasing amount of time to complete each test. By the 11th iteration, the browser took twice as long to finish the benchmark as it did when it first started.


Expected results:

The time required to complete each test should have remained pretty constant.

I don't understand why do you mention "leak" in the summary while there is nothing memory related in the comment.

Please provide a testcase or a public URL for that benchmark test.
