jag har kört denna: http://tools.percona.com vilket verkar ha förbättrat allt avsevärt.
Jag körde dock mysqltune och den visar detta.

Någon som kan hjälpa mig att ställa in det "rätt". Vore väldigt tacksam för hjälpen.

mySQL config filen nu

#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
# 
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...
# Remember to edit /etc/mysql/debian.cnf when changing the socket location.

-------- Performance Metrics -------------------------------------------------
[--] Up for: 21h 14m 4s (15M q [198.778 qps], 1M conn, TX: 36B, RX: 3B)
[--] Reads / Writes: 95% / 5%
[--] Total buffers: 74.0M global + 2.7M per thread (500 max threads)
[OK] Maximum possible memory usage: 1.4G (17% of installed RAM)
[OK] Slow queries: 0% (0/15M)
[OK] Highest usage of available connections: 8% (40/500)
[OK] Key buffer size / total MyISAM indexes: 16.0M/2.5M
[OK] Key buffer hit rate: 100.0% (87M cached / 4K reads)
[!!] Query cache efficiency: 0.0% (0 cached / 12M selects)
[OK] Query cache prunes per day: 0
[!!] Sorts requiring temporary tables: 11% (147K temp sorts / 1M sorts)
[!!] Joins performed without indexes: 286717
[!!] Temporary tables created on disk: 48% (641K on disk / 1M total)
[OK] Thread cache hit rate: 97% (32K created / 1M connections)

[OK] Open file limit used: 1% (674/65K)
[OK] Table locks acquired immediately: 99% (15M immediate / 15M locks)

-------- Recommendations -----------------------------------------------------
General recommendations:
    Add skip-innodb to MySQL configuration to disable InnoDB
    Run OPTIMIZE TABLE to defragment tables for better performance
    MySQL started within last 24 hours - recommendations may be inaccurate
    Enable the slow query log to troubleshoot bad queries
    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:
    query_cache_limit (> 1M, or use smaller result sets)
    sort_buffer_size (> 1M)
    read_rnd_buffer_size (> 256K)
    join_buffer_size (> 128.0K, or always use indexes with joins)
    tmp_table_size (> 32M)
    max_heap_table_size (> 32M)
    table_cache (> 4096)

Tack på förhand!

Ska tillägga att servern har 8 GB minne och 5 GB har jag satt till mysql.
Processorn är en gammal en med två kärnor.

Jag connectar från mig själv till servern med radioprogrammet, därför kan jag inte sätta den på bind 127.0
