Sehr geehrte Community,
ich haben einen Server
Intel E2620 mit 12 Cores inkl der Virtuellen Threads.
64 GB DDR3 ECC RAM
1 Gbit Leitung
Plesk 12 ist Installiert sowie Debian 7.7
Die Anbindung zum Storage ist mit 4x 1 Gbit angebunden.
Dann ist ein Storage mit Nexenta und 16 x 2 TB Festplatten zzgl. SSD als CACHE Platten.
Die Performance ist soweit ok.
Wir haben einen Online Shop mit ca 200000 T. (CSV Datei knapp 350MB) Artikel wenn wir den CSV Import machen dauert der Import knapp 4 Stunden
Die I/O Waits sind nicht einmal bei 1
aber das dauert einfach, ist zu Langsam.
Ich habe diese Werte nach langen hin und her mit Tuningprimer angepasst aber irgendwas übersehe ich oder ist das normal und MYSQl kann nicht schneller. Der Shop ist ein Gambio GX2 angepasst Version

Code:
MySQL Version 5.5.40-0+wheezy1-log x86_64
Uptime = 1 days 0 hrs 2 min 30 sec

SLOW QUERIES
The slow query log is enabled.
Current long_query_time = 2.000000 sec.
You have 1061397 out of 12279617 that take longer than 2.000000 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/doc/refman/5.5/en/point-in-time-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 = 151
Current threads_connected = 1
Historic max_used_connections = 12
The number of used connections is 7% 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
INNODB STATUS
Current InnoDB index space = 14 M
Current InnoDB data space = 110 M
Current InnoDB buffer pool free = 97 %
Current innodb_buffer_pool_size = 4.00 G
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 : 4.92 G
Configured Max Per-thread Buffers : 1.20 G
Configured Max Global Buffers : 4.82 G
Configured Max Memory Limit : 6.03 G
Physical Memory : 15.71 G
Max memory limit seem to be within acceptable norms
KEY BUFFER
Current MyISAM index space = 422 M
Current key_buffer_size = 512 M
Key cache miss rate is 1 : 7363
Key buffer free ratio = 18 %
Your key_buffer_size seems to be too high.
Perhaps you can use these resources elsewhere
QUERY CACHE
Query cache is enabled
Current query_cache_size = 320 M
Current query_cache_used = 125 M
Current query_cache_limit = 4 M
Current Query cache Memory fill ratio = 39.35 %
Current query_cache_min_res_unit = 8 K
MySQL won't cache query results that are larger than query_cache_limit in size
SORT OPERATIONS
Current sort_buffer_size = 1 M
Current read_rnd_buffer_size = 1 M
Sort buffer seems to be fine
JOINS
Current join_buffer_size = 2.00 M
You have had 104 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 = 1024000 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_open_cache = 524288 tables
Current table_definition_cache = 524288 tables
You have a total of 1324 tables
You have 2547 open tables.
The table_cache value seems to be fine
TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 16 M
Of 56738 temp tables, 27% were created on disk
Perhaps you should increase your tmp_table_size and/or max_heap_table_size
to reduce the number of disk-based temporary tables
Note! BLOB and TEXT columns are not allow in memory tables.
If you are using these columns raising these values might not impact your
ratio of on disk temp tables.
TABLE SCANS
Current read_buffer_size = 4 M
Current table scan ratio = 67134 : 1
read_buffer_size seems to be fine
TABLE LOCKING
Current Lock Wait ratio = 1 : 5078
Your table locking seems to be fine
