Server has been running for over 48hrs.
It should be safe to follow these recommendations

SLOW QUERIES
The slow query log is NOT enabled.
Current long_query_time = 10.000000 sec.
You have 0 out of 5271557 that take longer than 10.000000 sec. to complete
[: 0.00000000000000000000: bad number
Your long_query_time seems to be fine

BINARY UPDATE LOG
The binary update log is enabled
Binlog sync is not enabled, you could loose binlog records during a server crash

WORKER THREADS
Current thread_cache_size = 8
Current threads_cached = 6
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 250
Current threads_connected = 3
Historic max_used_connections = 10
The number of used connections is 4% of the configured maximum.
You are using less than 10% of your configured max_connections.
Lowering max_connections could help to avoid an over-allocation of memory
See "MEMORY USAGE" section to make sure you are not over-allocating

No InnoDB Support Enabled!

MEMORY USAGE
Max Memory Ever Allocated : 3.57 G
Configured Max Per-thread Buffers : 3.73 G
Configured Max Global Buffers : 3.42 G
Configured Max Memory Limit : 7.16 G
Physical Memory : 8.00 G
Max memory limit seem to be within acceptable norms

KEY BUFFER
Current MyISAM index space = 14 M
Current key_buffer_size = 384 M
Key cache miss rate is 1 : 7256
Key buffer free ratio = 79 %
Your key_buffer_size seems to be fine

QUERY CACHE
Query cache is enabled
Current query_cache_size = 32 M
Current query_cache_used = 17 M
Current query_cache_limit = 512 K
Current Query cache Memory fill ratio = 53.15 %
Current query_cache_min_res_unit = 4 K
Query Cache is 30 % fragmented
Run "FLUSH QUERY CACHE" periodically to defragment the query cache memory
If you have many small queries lower 'query_cache_min_res_unit' to reduce fragmentation.
MySQL won't cache query results that are larger than query_cache_limit in size

SORT OPERATIONS
Current sort_buffer_size = 4 M
Current read_rnd_buffer_size = 8 M
Sort buffer seems to be fine
