24核心和MYSQL使用1上INSERT

您好，我的服務器有24核心和32GB的內存。我一次做多個「插入選擇」5千萬行。這需要大約15小時的查詢，但它只有100％的CPU只有一個CPU，我試圖讓MySQL（5.5）（InnoDB）使用更多的資源。24核心和MYSQL使用1上INSERT

我已經閱讀了關於它的多個線程，但我沒有得到它的工作。

大多數信息都是關於加入innodb_thread_concurrency = 0 但我仍然沒有結果。

port  = 3306 
socket  = /var/run/mysqld/mysqld.sock 

[mysqld_safe] 
socket  = /var/run/mysqld/mysqld.sock

[mysqld] 
user  = mysql 
pid-file = /var/run/mysqld/mysqld.pid

myisam-recover   = BACKUP 
table_cache   = 800 

query_cache_limit = 5000M 
query_cache_size = 1600M

您可能對[dba.stackexchange.com]更多的運氣（http://dba.stackexchange.com） –

看起來更好地滿足在[數據庫管理] （http://dba.stackexchange.com/）類別。 –

試試這個參數：

innodb_io_capacity=5000 (or even 20000 depending on your IO subsystem) 
innodb_buffer_pool_size=4G (for example) 
innodb_log_file_size=1G 
innodb_write_io_threads = 64 
innodb_read_io_threads = 64 
innodb_thread_concurrency = 0
