-------- Recommendations ---------------------------------------------------------------------------
General recommendations:
MySQL started within last 24 hours - recommendations may be inaccurate
Reduce or eliminate unclosed connections and network issues
Configure your accounts with ip or subnets only, then update your configuration with skip-name-resolve=1
Variables to adjust:
query_cache_size (=0)
query_cache_type (=0)
query_cache_limit (> 1M, or use smaller result sets)
innodb_log_file_size * innodb_log_files_in_group should be equals to 1/4 of buffer pool size (=64M) if possible.
