There isn't enough information in this bug report for it to be useful. The testcase seems to be just writing out a DIV repeatedly by setting innerHTML, and there are existing performance bugs on that. There's no evidence that this is a security issue.

On trunk, I get  appr. 11500ms, while on branch I get 4500ms.
Reopening bug, I agree this might very well turn out to be a duplicate, but it isn't incomplete.

See bug 386802. Martijn, were you using the trunk build with the fix for bug 386802?
It still takes appr. 11500 ms with 2007-07-06 trunk build (which is after the fix from bug 386802).
I've tried narrowing down the regression range. On Win2k, going from trunk build 2007-04-30 to 2007-05-01 times jump from ~12400 to ~23500 ms.

Here's a bonsai query:

I think this is a regression from bug 368247. 

Just removing these border styles from "#bodyScroll .row" class, the time drops to 18000 ms.

	border-right-width: 1px;
	border-right-style: solid;
	border-right-color: #000000;
	border-bottom-width: 1px;
	border-bottom-style: solid;
	border-bottom-color: #999999;

Ok, thanks for finding out, Marius.
I think there is enough info to confirm this bug.

Test case takes about 4,3s on both Chrome and FF. Perf improved a lot over the last 5 years :-)
