Ok, jetzt habe ich die Werte erhalten:
-- MYSQL PERFORMANCE TUNING PRIMER --
- By: Matthew Montgomery -
MySQL Version 4.1.22-max-log i686
Uptime = 2 days 17 hrs 42 min 22 sec
Avg. qps = 10
Total Questions = 2597696
Threads Connected = 1
Server has been running for over 48hrs.
It should be safe to follow these recommendations

runtime variables effects performance visit:

SLOW QUERIES
Current long_query_time = 5 sec.
You have 303 out of 2597708 that take longer than 5 sec. to complete
The slow query log is enabled.
Your long_query_time seems to be fine
WORKER THREADS
Current thread_cache_size = 16
Current threads_cached = 15
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine
MAX CONNECTIONS
Current max_connections = 500
Current threads_connected = 1
Historic max_used_connections = 24
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
MEMORY USAGE
Max Memory Ever Allocated : 306 M
Configured Max Per-thread Buffers : 2 G
Configured Max Global Buffers : 202 M
Configured Max Memory Limit : 2 G
Total System Memory : 4.98 G
Max memory limit seem to be within acceptable norms
KEY BUFFER
Current MyISAM index space = 169 M
Current key_buffer_size = 128 M
Key cache miss rate is 1 : 2983
Key buffer fill ratio = 52.00 %
Your key_buffer_size seems to be fine
QUERY CACHE
Query cache is enabled
Current query_cache_size = 64 M
Current query_cache_used = 20 M
Current query_cach_limit = 2 M
Current Query cache fill ratio = 32.64 %
MySQL won't cache query results that are larger than query_cache_limit in size
SORT OPERATIONS
Current sort_buffer_size = 2 M
Current record/read_rnd_buffer_size = 256 K
Sort buffer seems to be fine
JOINS
Current join_buffer_size = 132.00 K
You have had 6 queries where a join could not use an index properly
You should enable "log-queries-not-using-indexes"
Then look for non indexed joins in the slow query log.
If you are unable to optimize your queries you may want to increase your
join_buffer_size to accommodate larger joins in one pass.
Note! This script will still suggest raising the join_buffer_size when
ANY joins not using indexes are found.
OPEN FILES LIMIT
Current open_files_limit = 2558 files
The open_files_limit should typically be set to at least 2x-3x
that of table_cache if you have heavy MyISAM usage.
Your open_files_limit value seems to be fine
TABLE CACHE
Current table_cache value = 1024 tables
You have a total of 166 tables
You have 202 open tables.
The table_cache value seems to be fine
TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 32 M
Of 172798 temp tables, 8% were created on disk
Effective in-memory tmp_table_size is limited to max_heap_table_size.
Created disk tmp tables ratio seems fine
TABLE SCANS
Current read_buffer_size = 1020 K
Current table scan ratio = 3202 : 1
read_buffer_size seems to be fine
TABLE LOCKING
Current Lock Wait ratio = 1 : 291
You may benefit from selective use of InnoDB.
If you have long running SELECT's against MyISAM tables and perform
frequent updates consider setting 'low_priority_updates=1'
