Doubts tuning MySQL Percona Server 5.5

[Antonio Fernández Pérez]

Hi list,

I have some doubts adjusting some MySQL variables.
​ I have checked MySQL status and maybe I should to increase some variables
...

For example:
InnoDB log waits is 103; innodb_log_buffer_size is 8M --> Maybe the next
best value could be 16M?
Table cache hit rate is 12%; Open_tables is 627; table_open_cache is 1024
--> Maybe the next best value could be 2048?
Key buffer hit rate is 93.7%; I have some queries that not using indexes ..
join_buffer_size is 4M --> Next best value? Maybe 8M and then check it
again?

That's all.

I hope your advices.

Regards,

Antonio.
