Motivation: We still have a room for improvement in PoolChunk.allocateRun() and Subpage.allocate(). Modifications: - Unroll the recursion in PoolChunk.allocateRun() - Subpage.allocate() makes use of the 'nextAvail' value set by previous free(). Result: - PoolChunk.allocateRun() optimization yields 10%+ improvements in allocation throughput for non-subpage allocations. - Subpage.allocate() optimization makes the subpage allocations for tiny buffers as fast as non-tiny buffers even when the pageSize is huge (e.g. 1048576) because it doesn't need to perform a linear search in most cases. |
