Comment #2 on issue 2639 by [email protected]: List is more inefficient than std::vector. Can't push work from Blink to V8 without regressing performance.
http://code.google.com/p/v8/issues/detail?id=2639

Sorting is the problem. Adding initial capacity doesn't help much.

No sorting, no initial capacity:
std: 168 microseconds
list: 83 microseconds

Sorting, initial capacity (only for V8 List):
std: 933 microseconds
list: 1702 microseconds
