24核，MYSQL使用1 on-INSERT

嗨，我的服务器有24个内核和32GB内存。 我一次在5000万行的SELECT中进行多次插入。 一个查询大约需要15个小时，但只需要一个CPU就可以100%运行，我正试图让mySQL5.5InnoDB使用更多的资源

我读了很多关于它的文章，但是我没有让它工作

大多数信息是关于添加innodb_线程_并发=0的 但我还是没有结果

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

[mysqld_safe]
socket      = /var/run/mysqld/mysqld.sock
nice        = 0

[mysqld]
user        = mysql
pid-file    = /var/run/mysqld/mysqld.pid
socket      = /var/run/mysqld/mysqld.sock
port        = 3306
basedir     = /usr
datadir     = /media/ssd/db
tmpdir      = /tmp
lc-messages-dir = /usr/share/mysql
skip-external-locking
innodb_buffer_pool_size=26G
innodb_thread_concurrency = 0

bind-address    = 127.0.0.1
#
# * Fine Tuning
#
key_buffer      = 1000M
max_allowed_packet  = 160M
thread_stack        = 192K
thread_cache_size       = 8
# This replaces the startup script and checks MyISAM tables if needed
# the first time they are touched
myisam-recover         = BACKUP
table_cache            = 800

query_cache_limit   = 5000M
query_cache_size    = 1600M
join_buffer_size    = 1000M


log_error = /var/log/mysql/error.log
# Here you can see queries with especially long duration
log_slow_queries    = /var/log/mysql/mysql-slow.log
long_query_time = 2   

请尝试以下参数：

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

你们可能会更幸运，因为你们看起来更适合这个类别。
