mysqltuner.pl Optimise help needed.

[howzit]

Hi, the past two weeks my server started to run on high server load and again I need to look at all the thingies that can be the cause thereof... Please help...

I notice that the slow queries is not problem!?!?!? ([OK] Slow queries: 0% (11K/31M))
But found that the slow query log grew to 10Mb in 4 days...?
Also why would it log something like:
# Time: 120820 12:59:54
# User
# Query_time: 0 Lock_time: 0 Rows_sent: 27 Rows_examined: 54
use thedb;
SELECT * FROM bdircats ORDER BY cname ASC;

What am I doing wrong?

mysqltuner.pl looks as follow and below it is contents of my.cnf :

-------- Recommendations -----------------------------------------------------
General recommendations:
    Run OPTIMIZE TABLE to defragment tables for better performance
    Reduce or eliminate persistent connections to reduce connection usage
    Adjust your join queries to always utilize indexes
    When making adjustments, make tmp_table_size/max_heap_table_size equal
    Reduce your SELECT DISTINCT queries without LIMIT clauses
    Increase table_cache gradually to avoid file descriptor limits
Variables to adjust:
    max_connections (> 200)
    wait_timeout (< 1800)
    interactive_timeout (< 28800)
    query_cache_size (> 128M)
    join_buffer_size (> 256.0K, or always use indexes with joins)
    tmp_table_size (> 64M)
    max_heap_table_size (> 64M)
    table_cache (> 1024)
