-------- Recommendations -----------------------------------------------------
General recommendations:
Run OPTIMIZE TABLE to defragment tables for better performance
MySQL started within last 24 hours - recommendations may be inaccurate
Enable the slow query log to troubleshoot bad queries
Adjust your join queries to always utilize indexes
Increase table_cache gradually to avoid file descriptor limits
Variables to adjust:
query_cache_limit (> 1M, or use smaller result sets)
query_cache_size (> 16M)
join_buffer_size (> 128.0K, or always use indexes with joins)
table_cache (> 64)
innodb_buffer_pool_size (>= 279M)My.cnf:

# The MySQL database server configuration file.

# You can copy this to one of:

# - "~/.my.cnf" to set user-specific options.

# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.

# For explanations see
