Hello,

Below are the results for my tuner script, I tried optimizing the tables but it just said that my innodb tables could not be updated.

Also can you please suggest the changes to the my.cnf.

Thank you for your time!

-------- Recommendations -----------------------------------------------------
General recommendations:
    Run OPTIMIZE TABLE to defragment tables for better performance
    Increasing the query_cache size over 128M may reduce performance
    Adjust your join queries to always utilize indexes
    When making adjustments, make tmp_table_size/max_heap_table_size equal
    Reduce your SELECT DISTINCT queries without LIMIT clauses
    Increase table_open_cache gradually to avoid file descriptor limits
    Read this before increasing table_open_cache over 64: http://bit.ly/1mi7c4C
Variables to adjust:
    query_cache_size (> 512M) [see warning above]
    join_buffer_size (> 16.0M, or always use indexes with joins)
    tmp_table_size (> 32M)
    max_heap_table_size (> 32M)
    table_open_cache (> 256)
    innodb_log_buffer_size (>= 8M)

Hi!

You could start with these values
query_cache_size = 1024M
    join_buffer_size = 32M
    tmp_table_size  = 128M
    max_heap_table_size  = 128M
    table_open_cache = 1024
    innodb_log_buffer_size = 32M

Regards,
