oprofile shows quite a bit more overhead in 2.4's ACL processing vs 2.3's. I'm thinking of streamlining things a bit, along these lines. Any thoughts?
Only a few loose ones:
A brief look shows some deep indirection, which may be harder for compilers to optimize due to possible aliasing among intervening writes. Maybe you should help by unpacking some more common expressions into local variables.
Profiling showed that the ACLCHECK branch didn't have any improvement over HEAD. Looks like it may not be worth the trouble.
Are you going to drop this?
