MySQL 性能:使用 MySQL 5.7 实现每秒 50 万查询
还有很多挑战摆在我们面前;-)
作为参考,我上述测试的硬件配置信息如下:
- Server : 32cores-HT (bi-thread) Intel 2300Mhz, 128GB RAM
- OS : Oracle Linux 6.2
- FS : 启用”noatime,nodiratime,nobarrier”挂载的EXT4
my.conf:
max_connections=4000 key_buffer_size=200M low_priority_updates=1 table_open_cache = 8000 back_log=1500 query_cache_type=0 table_open_cache_instances=16 # files innodb_file_per_table innodb_log_file_size=1024M innodb_log_files_in_group = 3 innodb_open_files=4000 # buffers innodb_buffer_pool_size=32000M innodb_buffer_pool_instances=32 innodb_additional_mem_pool_size=20M innodb_log_buffer_size=64M join_buffer_size=32K sort_buffer_size=32K # innodb innodb_checksums=0 innodb_doublewrite=0 innodb_support_xa=0 innodb_thread_concurrency=0 innodb_flush_log_at_trx_commit=2 innodb_max_dirty_pages_pct=50 innodb_use_native_aio=1 innodb_stats_persistent = 1 innodb_spin_wait_delay= 6 / 96 # perf special innodb_adaptive_flushing = 1 innodb_flush_neighbors = 0 innodb_read_io_threads = 4 innodb_write_io_threads = 4 innodb_io_capacity = 4000 innodb_purge_threads=1 innodb_adaptive_hash_index=0 # monitoring innodb_monitor_enable = '%' performance_schema=OFF
如果你需要的话,Linux Sysbench的二进制版本在这里:
- Sysbench-0.4.13-lux86
- Sysbench-0.4.8-lux86
使用UNIX socket来运行Point-Selects测试的Sysbench命令如下(在parallel中启动8个进程):
LD_PRELOAD=/usr/lib64/libjemalloc.so /BMK/sysbench-0.4.8 --num-threads=$1 --test=oltp --oltp-table-size=10000000 \ --oltp-dist-type=uniform --oltp-table-name=sbtest_10M_$n \ --max-requests=0 --max-time=$2 --mysql-socket=/SSD_raid0/mysql.sock \ --mysql-user=dim --mysql-password=dim --mysql-db=sysbench \ --mysql-table-engine=INNODB --db-driver=mysql \ --oltp-point-selects=1 --oltp-simple-ranges=0 --oltp-sum-ranges=0 \ --oltp-order-ranges=0 --oltp-distinct-ranges=0 --oltp-skip-trx=on \ --oltp-read-only=on run > /tmp/test_$n.log &
使用IP端口来运行Point-Selects测试的Sysbench命令如下(在parallel中启动8个进程):
LD_PRELOAD=/usr/lib64/libjemalloc.so /BMK/sysbench-0.4.13 --num-threads=$1 --test=oltp --oltp-table-size=10000000 \ --oltp-dist-type=uniform --oltp-table-name=sbtest_10M_$n \ --max-requests=0 --max-time=$2 --mysql-host=127.0.0.1 --mysql-port=5700 \ --mysql-user=dim --mysql-password=dim --mysql-db=sysbench \ --mysql-table-engine=INNODB --db-driver=mysql \ --oltp-point-selects=1 --oltp-simple-ranges=0 --oltp-sum-ranges=0 \ --oltp-order-ranges=0 --oltp-distinct-ranges=0 --oltp-skip-trx=on \ --oltp-read-only=on run > /tmp/test_$n.log &
