Jednak problem występuje dalej, z top'a:

23418 mysql 20 0 139m 43m 4068 S 57 2.2 1331:06 mysqld

57- CPU %
2.2- RAM %


Z panelu OVH:
Obciążenie serwera: 100 %
Obciążenie RAM: 35 %
Obciążenie SWAP: 4 %

Oczywiście forum chodzi wolniej niż powinno :/

Wiec pewnie pozostaje optymalizacja zapytan, dodanie indexow itp. A jesli i to nie pomoze, to czas pomyslec nad zmiana maszyny/dyskow.

OK, jak będę przedłużał dzierżawę serwera to wezmę 2XL zobaczymy jak na nim będzie.

Uptime = 4 days 6 hrs 30 min 40 sec

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 sec.
You have 0 out of 11295261 that take longer than 10 sec. to complete
Your long_query_time seems to be fine

BINARY UPDATE LOG
The binary update log is NOT enabled.
You will not be able to do point in time recovery
See http://dev.mysql.com...e-recovery.html

WORKER THREADS
Current thread_cache_size = 8
Current threads_cached = 7
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 100
Current threads_connected = 1
Historic max_used_connections = 101
The number of used connections is 101% of the configured maximum.
You should raise max_connections

INNODB STATUS
Current InnoDB index space = 0 bytes
Current InnoDB data space = 0 bytes
Current InnoDB buffer pool free = 65 %
Current innodb_buffer_pool_size = 8 M
Depending on how much space your innodb indexes take up it may be safe
to increase this value to up to 2 / 3 of total system memory

MEMORY USAGE
Max Memory Ever Allocated : 307 M
Configured Max Per-thread Buffers : 262 M
Configured Max Global Buffers : 42 M
Configured Max Memory Limit : 304 M
Physical Memory : 3.83 G
Max memory limit seem to be within acceptable norms

KEY BUFFER
Current MyISAM index space = 2 M
Current key_buffer_size = 16 M
Key cache miss rate is 1 : 2441
Key buffer free ratio = 81 %
Your key_buffer_size seems to be fine

QUERY CACHE
Query cache is enabled
Current query_cache_size = 16 M
Current query_cache_used = 5 M
Current query_cache_limit = 1 M
Current Query cache Memory fill ratio = 32.22 %
Current query_cache_min_res_unit = 4 K
MySQL won't cache query results that are larger than query_cache_limit in size

SORT OPERATIONS
Current sort_buffer_size = 2 M
Current read_rnd_buffer_size = 256 K
Sort buffer seems to be fine

JOINS
Current join_buffer_size = 132.00 K
You have had 1 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 = 1024 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 = 64 tables
You have a total of 73 tables
You have 64 open tables.
Current table_cache hit rate is 2%
, while 100% of your table cache is in use
You should probably increase your table_cache

TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 32 M
Of 4077 temp tables, 11% 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 = 128 K
Current table scan ratio = 307 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 285
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'
If you have a high concurrency of inserts on Dynamic row-length tables
consider setting 'concurrent_insert=2'.

co powinienem zmienic?? :>
