Hallo liebe Serversupportforum-User,
nach mehreren Tagen Internetsuche (wodurch ich auf dieses Forum gestoßen bin) konnte ich mein Problem mit meinen VServer (von ispone-business) nicht lösen.
Der Server hat insgesamt 512MB RAM und 15GB Speicherplatz zur Verfügung.
Ich hoste momentan auf dem Server ca. 80 Foren (auf phpbb-Basis). Zu hohen Besucherzeiten (vorallem ab 18 Uhr) kommt es zu extrem langen Ladezeiten. Um dieses Problem zu lösen, habe ich bereits das Tuning-Primer-Skript ausprobiert und folgende my.cnf erstellt:
und hier die momentane Ausgabe des Tuning-Primer-Skriptes:
Könnt ihr mir weiterhelfen und Verbesserungsschläge für die Einstellungen posten?
Wäre für jede Hilfe dankbar.
MfG
Raphael

SLOW QUERIES
The slow query log is [COLOR="Red"]NOT[/COLOR] enabled.
Current long_query_time = 4 sec.
You have [COLOR="Red"]529[/COLOR] out of [COLOR="Red"]8710[/COLOR] that take longer than 4 sec. to complete
Your long_query_time seems to be fine
BINARY UPDATE LOG
The binary update log is [COLOR="Red"]NOT[/COLOR] enabled.
[COLOR="Red"]You will not be able to do point in time recovery[/COLOR]
[COLOR="Yellow"]See http://dev.mysql.com/doc/refman/5.0/en/point-in-time-recovery.html[/COLOR]
WORKER THREADS
Current thread_cache_size = 8
Current threads_cached = 5
Current threads_per_sec = 0
Historic threads_per_sec = 0
[COLOR="Green"]Your thread_cache_size is fine[/COLOR]
MAX CONNECTIONS
Current max_connections = 20
Current threads_connected = 1
Historic max_used_connections = 6
The number of used connections is 30% of the configured maximum.
[COLOR="Green"]Your max_connections variable seems to be fine.[/COLOR]
MEMORY USAGE
Max Memory Ever Allocated : 81 M
Configured Max Per-thread Buffers : 77 M
Configured Max Global Buffers : 58 M
Configured Max Memory Limit : 135 M
Physical Memory : 512.20 M
[COLOR="Green"]Max memory limit seem to be within acceptable norms[/COLOR]
KEY BUFFER
Current MyISAM index space = 311 M
Current key_buffer_size = 16 M
Key cache miss rate is 1 : 14
Key buffer fill ratio = 10.00 %
[COLOR="Red"]Your key_buffer_size seems to be too high.
Perhaps you can use these resources elsewhere[/COLOR]
QUERY CACHE

Current query_cache_limit = 32 M
Current Query cache Memory fill ratio = 6.59 %

[COLOR="Red"]Your query_cache_size seems to be too high.
Perhaps you can use these resources elsewhere[/COLOR]
[COLOR="Yellow"]MySQL won't cache query results that are larger than query_cache_limit in size[/COLOR]
SORT OPERATIONS
Current sort_buffer_size = 2 M
Current read_rnd_buffer_size = 256 K
[COLOR="Green"]Sort buffer seems to be fine[/COLOR]
JOINS
Current join_buffer_size = 512.00 K
You have had 3 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.
[COLOR="Red"]Note! This script will still suggest raising the join_buffer_size when
ANY joins not using indexes are found.[/COLOR]
OPEN FILES LIMIT
Current open_files_limit = 25600 files
[COLOR="Yellow"]The open_files_limit should typically be set to at least 2x-3x
that of table_cache if you have heavy MyISAM usage.[/COLOR]
[COLOR="Green"]Your open_files_limit value seems to be fine[/COLOR]
TABLE CACHE
Current table_cache value = 10240 tables
You have a total of 4209 tables
You have 4231 open tables.
[COLOR="Green"]The table_cache value seems to be fine[/COLOR]
TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 16 M
Of 362 temp tables, 13% were created on disk
[COLOR="Green"]Created disk tmp tables ratio seems fine[/COLOR]

Current read_buffer_size = 1020 K
Current table scan ratio = 3137 : 1
[COLOR="Green"]read_buffer_size seems to be fine[/COLOR]
TABLE LOCKING
Current Lock Wait ratio = 0 : 8887
Your table locking seems to be fineKönnt ihr mir weiterhelfen und Verbesserungsschläge für die Einstellungen posten?
