Your slab allocator work looks very interesting. Given that the performance is comparable to what we are currently running, it seems like a big step forward. The current statistics that I find most useful are (in order), the number of current allocations, the high watermark for allocations, and the total number of allocations made. The number of current allocations needs to be correct and should be done under a lock. The high watermark and total number of allocations need not be precisely correct, so could well be done without a lock. The occational missed count, or a slightly low high watermark would not much matter.
