Acl::SetRule performance is very slow

[steverhoades]

We are dealing with rules in the 70k - 100k 1k - 2k range. It currently takes setRule around 2.5 seconds to process all of these rules.

I have been able to increase the performance of this method by roughly 40% by simply eliminating the use of array_merge.

Suggested Change Acl line:580 to:

foreach($children as $child) {
    $resources[] = $child;
}

Suggestions on how this method can be improved further would be great appreciated. The tree that is being generated takes approximately 100-130ms to serialize/unserialize.

Note: Acl configuration will be cached in Production.

EDIT:
Sorry rules are in the 1500 - 2000 range. Roughly 300 roles and 300 resources.

Here is the current benchmarks running 1538 rules.

@steverhoades you can try patching the line you suggested, but you'd need to verify edge cases with string keys and array keys first.

[steverhoades]

@Ocramius good point.
How about:

foreach($children as $key => $child) {
    $resources[$key] = $child;
}

[Ocramius]

@steverhoades can work, yes.

[Ocramius]

@steverhoades again, I'd start from the tests: the snippet above overwrites numeric keys.

[steverhoades]

@Ocramius I should know better, I'll check out the tests. From reading the code it appears as though the keys should be resourceIds... perhaps i have that wrong.
