For our automated MariaDB/MySQL sysbench benchmark tests, we use sysbench from lp:sysbench. This page describes the basic parameters and configuration we use.

You can find the automation wrapper scripts we use for running sysbench in lp:mariadb-tools

Current general parameters

table_open_cache = 512
thread_cache = 512
query_cache_size = 0
query_cache_type = 0

Current InnoDB parameters

innodb_data_home_dir = /data/mysql/
innodb_data_file_path = ibdata1:128M:autoextend
innodb_log_group_home_dir = /data/mysql/
innodb_buffer_pool_size = 1024M
innodb_additional_mem_pool_size = 32M
innodb_log_file_size = 256M
innodb_log_buffer_size = 16M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50
innodb_doublewrite = 0
innodb_flush_method = O_DIRECT
innodb_thread_concurrency = 0
innodb_max_dirty_pages_pct = 80

Compile

Install MariaDB or MySQL to /usr/local and make a symlink to /usr/local/mysql. Please use non-debug version! On Mac OS X we currently need automake1.10.

./autogen.sh
./configure \
  --without-drizzle \
  --with-mysql-includes=/usr/local/mysql/include/mysql \
  --with-mysql-libs=/usr/local/mysql/lib/mysql
make
optionally: make install

Start and prepare database to use

mysqladmin -uroot drop sbtest
mysqladmin -uroot create sbtest

Tests

We use the latest sysbench with Lua scripting support. Therefore the test names differ from sysbench <= 0.4. To get reasonable results we use a run time of 5 minutes.

We run the tests with 1, 4, 8, 16, 32, 64, and 128 threads.

NUM_THREADS="1 4 8 16 32 64 128"
SYSBENCH_TESTS="delete.lua \
  insert.lua \
  oltp_complex_ro.lua \
  oltp_complex_rw.lua \
  oltp_simple.lua \
  select.lua \
  update_index.lua \
  update_non_index.lua"

  --mysql-table-engine=InnoDB \

  --num-threads=$NUM_THREADS \
  run

Custom added tests

We created a couple of custom tests for SysBench:

  • select_random_ranges.lua
  • select_random_points.lua

Both of these have been added to the latest SysBench v0.5 repository.
