#>　　
# Do not set it larger than 30% of your available memory, as some memory

# MyISAM tables, you should still set it to 8-64M as it will also be

#*** INNODB Specific options ***
　　
# Use this option if you have a MySQL server with InnoDB support enabled
　　
# but you do not plan to use it. This will save memory and disk space
　　
# and speed up some things.
　　
#skip-innodb
　　
# Additional memory pool that is used by InnoDB to store metadata
　　
# information.  If InnoDB requires more memory for this purpose it will
　　
# start to allocate it from the OS.  As this is fast enough on most
　　
# recent operating systems, you normally do not need to change this
　　
# value. SHOW INNODB STATUS will display the current amount used.
　　
innodb_additional_mem_pool_size=2M
　　
# If set to 1, InnoDB will flush (fsync) the transaction logs to the
　　
# disk at each commit, which offers full ACID behavior. If you are
　　
# willing to compromise this safety, and you are running small
　　
# transactions, you may set this to 0 or 2 to reduce disk I/O to the
　　
# logs. Value 0 means that the log is only written to the log file and
　　
# the log file flushed to disk approximately once per second. Value 2
　　
# means the log is written to the log file at each commit, but the log
　　
# file is only flushed to disk approximately once per second.
　　
innodb_flush_log_at_trx_commit=1

　　
# The>　　
# it is full, InnoDB will have to flush it to disk. As it is flushed
　　
# once per second anyway, it does not make sense to have it very large
　　
# (even with long transactions).
　　
innodb_log_buffer_size=1M
　　
# InnoDB, unlike MyISAM, uses a buffer pool to cache both indexes and
　　
# row data. The bigger you set this the less disk I/O is needed to
　　
# access data in tables. On a dedicated database server you may set this

　　
# parameter up to 80% of the machine physical memory>　　
# too large, though, because competition of the physical memory may
　　
# cause paging in the operating system.  Note that on 32bit systems you
　　
# might be limited to 2-3.5G of user level memory per process, so do not
　　
# set it too high.

# Number of threads allowed inside the InnoDB kernel. The optimal value
