optimize mysql on server

We are looking for person to optimize our server mysql. we have 64gb memory installed but still the site is loading very slow due to mysql.

You will connect through teamviewer and do necessary adjustments so mysql works faster.

Here is our output for mysql tuner.

-------- Recommendations -----------------------------------------------------

General recommendations:

Run OPTIMIZE TABLE to defragment tables for better performance

Enable the slow query log to troubleshoot bad queries

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

Set thread_cache_size to 4 as a starting value

Increase table_cache gradually to avoid file descriptor limits

Variables to adjust:

query_cache_size (>= 8M)

join_buffer_size (> [url removed, login to view], or always use indexes with joins)

tmp_table_size (> 16M)

max_heap_table_size (> 16M)

thread_cache_size (start at 4)

table_cache (> 400)
