mysql  sysbench 测试

最近尝试对mariadb 10.0  进行sysbench 的 OLTP 的 RW complex 测试，

测试的机器配置如下：

cpu : 80核
内存 ： 64G
硬盘 ： SAS RAID1

测试工具：

sysbench-0.4.12

操作系统调优：

echo deadline >/sys/block/sda/queue/scheduler
ulimit -n 10240


数据生成语句为：

./sysbench --test=oltp --oltp-table-size=20000000 --mysql-host=127.0.0.1 --mysql-port=3306 --mysql-user=root --mysql-db=test --db-driver=mysql prepare

调优之后的配置文件如下：

[client]
port            = 3306
socket          = /tmp/mysql.sock

[mysqld]
port            = 3306
socket          = /tmp/mysql.sock
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
skip-external-locking
skip-name-resolve
key_buffer_size = 512M
thread_cache_size = 3000
max_connections = 20480
lower_case_table_names = 1

server-id       = 1

thread_handling=pool-of-threads
thread_pool_max_threads=1500

innodb_log_file_size = 4G
innodb_log_buffer_size = 256M
innodb_buffer_pool_size = 30G
innodb_buffer_pool_instances = 1
innodb_flush_log_at_trx_commit = 0
innodb_file_per_table=1
innodb_locks_unsafe_for_binlog = 1
innodb_thread_concurrency = 28
innodb_flush_method= O_DIRECT
innodb_io_capacity=600
innodb_log_block_size=2048
innodb_read_io_threads=16
innodb_write_io_threads=16

innodb_support_xa=0
innodb_change_buffering=all
innodb_checksum_algorithm=none
innodb_doublewrite = false

#innodb_adaptive_hash_index = 0

max_prepared_stmt_count=1048576

[mysqldump]
quick
max_allowed_packet = 16M

[mysql]
no-auto-rehash



测试结果为：
