A ovo je moj fajl. I ok, sad treba da cekam 24h bar pa ponovo da proverim sa mysqltuner

Code:

early-plugin-load=keyring_file.so

key_buffer_size        = 32M
max_allowed_packet    = 256M

thread_cache_size       = 300
max_connections        = 1000
table_open_cache = 1200
query_cache_limit    = 48M
query_cache_type = 1
query_cache_size        = 96M
join_buffer_size = 128M
tmp_table_size = 512M
max_heap_table_size = 512M
#myisam-recover         = BACKUP
#thread_stack        = 192K
#log_slow_queries    = /var/log/mysql/mysql-slow.log
#long_query_time = 1
#expire_logs_days    = 10
#max_binlog_size         = 100M
#innodb_buffer_pool_size = 35G
#innodb_log_file_size = 8G
#innodb_log_buffer_size=1M
##innodb_flush_log_at_trx_commit = 1
##########################
innodb_read_io_threads=4
innodb_write_io_threads=8  #To stress the double write buffer
innodb_buffer_pool_size=24G
innodb_buffer_pool_load_at_startup=ON
innodb_log_file_size = 32M #Small log files, more page flush
innodb_log_files_in_group=2
innodb_file_per_table=1
innodb_log_buffer_size=8M
innodb_flush_method=O_DIRECT
innodb_flush_log_at_trx_commit=0



Ovo sto je komentovano, tako mi je bilo sa mysql 5.7, ali za sada je komentovano.
Ove innodb vrednosti, ne znam sta rade, njih sam jos na pocetku posle upgrade iskopirao odnekud.
Mozda sam preterao sa nekim vredsnostima? :)
Ali mysqltuner kad god resetujem servis, je savetovao jos da povecam...


Bio bih veoma zahvalan ako biste prosli kroz ovo sa mnom :)
