      Description

      In testing the performance of TokuDB tables using the MariaDB builds (available from mariadb.org) I noticed significant performance regressions. The following is for Sysbench (data > cache, IO bound):
      workload = read/write
      tables = 16
      distribution = uniform
      rows / table = 10 million
      tokudb_cache_size = 8G
      tokudb_directio = 1
      tokudb_read_block_size = 64K
      tokudb_row_format = tokudb_lzma
      performance_schema=off

      Table are bulk-loaded, then ran the test for 64 and 128 client threads, 5 minutes per thread count. Results as follows:

      MariaDB 10.0.8 : source = mariadb.org
      64 threads, 78.0 tps
      128 threads, 95.6 tps

      MariaDB 5.5.36 : source = mariadb.org
      64 threads, 78.4 tps
      128 threads, 95.8 tps

      MariaDB 5.5.30 : source = tokutek.com
      64 threads, 132.3 tps
      128 threads, 161.5 tps

      MySQL 5.5.30 : source = tokutek.com
      64 threads, 134.8 tps
      128 threads, 164.1 tps

      MySQL 5.5.36 : source = tokutek.com
      64 threads, 131.2 tps
      128 threads, 161.4 tps
