    Tell me for a server with 6 GB of RAM and 5 Core CPU and CentOs 6.8

    Total processors: 5
    each processor:
    Vendor GenuineIntel
    Name Common KVM processor
    Speed 3192.746 MHz
    Cache 4096 KB
    --------------------
    Memory: 5963940k/6815744k available
    and my.cnf is:
    Code:
    [mysqld]
    log-error=/var/lib/mysql/error.log
    innodb_file_per_table=1
    default-storage-engine=MyISAM
