Hi, we have a VPS with 2.5 GHz and 3 G RAM
We will expand to 4.5 GHz and 7.5 G RAM as the CPU Mysql comes up 146%
MySQLTuner Report with 2.5 GHz and 3 G RAM
How better to change the configuration of power and the actual power

-------- Recommendations -----------------------------------------------------
General recommendations:
Run OPTIMIZE TABLE to defragment tables for better performance
MySQL started within last 24 hours - recommendations may be inaccurate
Adjust your join queries to always utilize indexes
Set thread_cache_size to 4 as a starting value
Increase table_cache gradually to avoid file descriptor limits
Variables to adjust:
key_buffer_size (> 16.4M)
query_cache_size (>= 8M)
join_buffer_size (> 128.0K, or always use indexes with joins)
thread_cache_size (start at 4)
table_cache (> 512)
innodb_buffer_pool_size (>= 167M)
Code:
[mysqld]
# safe-show-database
bind-address=127.0.0.1
log-slow-queries
max_connections=500
default-storage-engine=MyISAM
innodb_file_per_table=1
open_files_limit=4300
table_cache=512
