Η ουσια ειναι οτι εαν η βαση δεν ειναι ηδη optimized απο την δημιουργια "το σχεδιαζμο", τοτε δεν το βοηθαει τιποτα.
Εγώ θα σου έλεγα Arxos να το δοκιμάσεις, δεν χάνεις τίποτα, ούτε (φαντάζομαι) υπάρχει κύνδινος κάποιας ζημιάς. Δεν θα σου κάνει τίποτα παραπάνω παρά έναν έλεγχο ρυθμίσεων και θα σου προτείνει να αλλάξεις κάποιες ρυθμίσεις για βελτίωση της ταχύτητας. Κάντο και πες μας αποτελέσματα.
SLOW QUERIESThe slow query log is NOT enabled.Current long_query_time = 10 sec.You have 11 out of 5525229 that take longer than 10 sec. to completeYour long_query_time may be too high, I typically set this under 5 sec.BINARY UPDATE LOGThe binary update log is NOT enabled.You will not be able to do point in time recoverySee http://dev.mysql.com/doc/refman/5.0/en/point-in-time-recovery.htmlMAX CONNECTIONSCurrent max_connections = 500Current threads_connected = 3Historic max_used_connections = 27The number of used connections is 5% 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 memorySee "MEMORY USAGE" section to make sure you are not over-allocatingQUERY CACHEQuery cache is supported but not enabledPerhaps you should set the query_cache_sizeJOINS./tuning-primer.sh: line 332: bc: command not foundCurrent join_buffer_size = KYou have had 2815 queries where a join could not use an index properlyYou 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 yourjoin_buffer_size to accommodate larger joins in one pass.Note! This script will still suggest raising the join_buffer_size whenANY joins not using indexes are found.TABLE CACHECurrent table_cache value = 4 tablesYou have a total of 233 tablesYou have 4 open tables.Current table_cache hit rate is 0%, while 100% of your table cache is in useYou should probably increase your table_cacheTEMP TABLES./tuning-primer.sh: line 332: bc: command not foundCurrent max_heap_table_size = M./tuning-primer.sh: line 332: bc: command not foundCurrent tmp_table_size = MOf 47286 temp tables, 30% were created on diskEffective in-memory tmp_table_size is limited to max_heap_table_size.Perhaps you should increase your tmp_table_size and/or max_heap_table_sizeto reduce the number of disk-based temporary tablesNote! BLOB and TEXT columns are not allow in memory tables.If you are using these columns raising these values might not impact yourratio of on disk temp tables.TABLE LOCKINGCurrent Lock Wait ratio = 1 : 1286You may benefit from selective use of InnoDB.If you have long running SELECT's against MyISAM tables and performfrequent updates consider setting 'low_priority_updates=1'If you have a high concurrency of inserts on Dynamic row-length tablesconsider setting 'concurrent_insert=2'.
