approved by: Marko rb://681 Coalescing of free buf_page_t descriptors can prove to be one severe bottleneck in performance of compression. One such workload where it hurts badly is DROP TABLE. This patch removes buf_page_t allocations from buf_buddy and uses ut_malloc instead. In order to further reduce overhead of colaescing we no longer attempt to coalesce a block if the corresponding free_list is less than 16 in size. |
