Does this include a large pages support?
I encountered a problem that the performance went down when several mega bytes were
assigned for each read buffer, read rnd buffer and sort buffer on a Nocona system. I
suspect that many TLB cache miss were happening at that time. Currently, MySQL only
supports large pages for InnoDB. If MySQL will have a slab allocator which supports large
pages like memcached, the performance will improve due to less TLB cache miss, won't it?
