A larger buffer pool requires less disk I/O to access the same table data more than once. On a dedicated database server, you might set the buffer pool size to 80% of the machine's physical memory size. Be aware of the following potential issues when configuring buffer pool size, and be prepared to scale back the size of the buffer pool if necessary.

innodb_buffer_pool_size     = 16G

#This sets the size of the InnoDB’s redo log files which, in MySQL world, are often called simply transaction logs. 
#And right until MySQL 5.6.8 the default value of innodb_log_file_size=5M was the single biggest InnoDB 
#performance killer. Starting with MySQL 5.6.8, the default was raised to 48M which, for many intensive systems, 
#is still way too low.
#As a rule of thumb you should set this to accommodate ~1-2h worth of writes and if you’re in a hurry, 
#having this set to 1-2G will give you pretty good performance with pretty much any workload.
innodb_log_file_size = 1G

# For MyISAM tables
tmpdir                      = /var/mysqltmp

# For MyISAM tables
mkdir /var/mysqltmp
id -u mysql
id -g mysql

Edit /etc/fstab

tmpfs           /var/mysqltmp                   tmpfs rw,gid=125,uid=117,size=16G,nr_inodes=10k,mode=0700 0 0

Tweak your Swap Settings

cat /proc/sys/vm/swappiness

The swappiness parameter configures how often your system swaps data out of RAM to the swap space. This is a value between 0 and 100 that represents a percentage.

With values close to zero, the kernel will not swap data to the disk unless absolutely necessary. Remember, interactions with the swap file are “expensive” in that they take a lot longer than interactions with RAM and they can cause a significant reduction in performance. Telling the system not to rely on the swap much will generally make your system faster.

Values that are closer to 100 will try to put more data into swap in an effort to keep more RAM space free. Depending on your applications’ memory profile or what you are using your server for, this might be better in some cases.
