测试参数:sysbench--test=/root/sysbench0.5/sysbench/tests/db/insert.lua--mysql-table-engine=innodb--oltp-table-size=1000000--max-requests=0--max-time=

测试参数:

sysbench --test=/root/sysbench0.5/sysbench/tests/db/insert.lua --mysql-table-engine=innodb --oltp-table-size=1000000 --max-requests=0 --max-time=300 --num-threads=16 --oltp-tables-count=10 --report-interval=10 --mysql-host=10.8.8.100 --mysql-port=3312 --mysql-user=admin --mysql-password=123456 --mysql-db=test run

10张100万行表,并发16个线程,纯插入操作。


MySQL参数:

sync_binlog = 0 innodb_flush_log_at_trx_commit = 0 innodb_flush_method = O_DIRECT innodb_flush_neighbors = 1 innodb_buffer_pool_size = 10G innodb_io_capacity = 500 innodb_log_file_size = 512M innodb_log_files_in_group = 3 innodb_log_buffer_size = 16M


普通复制延迟:
