mysql 基準測試-01

1、穩定性測試對比組

percona 5.6.36VSmysql 5.5.47

同樣設置下，運行基準測試，對比各自穩定性

2、不能參數設置，性能對比組

第一組修改參數
sort_buffer_size = 32M
join_buffer_size = 1M
read_buffer_size = 16M
read_rnd_buffer_size = 16M
myisam_sort_buffer_size = 8M

transaction-isolation = REPEATABLE-READ

innodb_io_capacity=200

innodb_flush_method =默認設置

innodb_log_buffer_size=8M

innodb_additional_mem_pool_size= 默認設置

第二組參數

sort_buffer_size = 4M
join_buffer_size = 1M
read_buffer_size = 4M
read_rnd_buffer_size = 4M
myisam_sort_buffer_size = 8M
transaction-isolation = REPEATABLE-READ
innodb_io_capacity=2000
innodb_flush_method = O_DSYNC/O_DIRECT
innodb_log_buffer_size=8M
innodb_additional_mem_pool_size=2M

3、性能優化效果

一組

sort_buffer_size = 32M
join_buffer_size = 1M
read_buffer_size = 16M
read_rnd_buffer_size = 16M
myisam_sort_buffer_size = 8M

transaction-isolation = REPEATABLE-READ

innodb_io_capacity=200

innodb_flush_method =默認設置

innodb_log_buffer_size=8M

innodb_additional_mem_pool_size= 默認設置

二組

sort_buffer_size = 4M
join_buffer_size = 1M
read_buffer_size = 4M
read_rnd_buffer_size = 4M
myisam_sort_buffer_size = 8M
transaction-isolation = REPEATABLE-READ

三組

innodb_io_capacity=2000
innodb_flush_method = O_DSYNC/O_DIRECT
innodb_log_buffer_size=8M
innodb_additional_mem_pool_size=2M
