I think that it's not problem with SELECT, because problem appears even when I turn off all queries in scripts.

I'll try to do soemthing with composite index.

Result of SHOW VARIABLES LIKE '%buffer%'

bulk_insert_buffer_size = 8388608
innodb_buffer_pool_dump_at_shutdown = OFF
innodb_buffer_pool_dump_now = OFF
innodb_buffer_pool_filename = ib_buffer_pool
innodb_buffer_pool_instances = 8
innodb_buffer_pool_load_abort = OFF
innodb_buffer_pool_load_at_startup = OFF
innodb_buffer_pool_load_now = OFF
innodb_buffer_pool_size = 68719476736
innodb_change_buffer_max_size = 25
innodb_change_buffering = all
innodb_log_buffer_size = 34359738368
innodb_sort_buffer_size = 1048576
join_buffer_size = 8589934592
key_buffer_size = 17179869184
myisam_sort_buffer_size = 8388608
net_buffer_length = 16384
preload_buffer_size = 32768
read_buffer_size = 131072
read_rnd_buffer_size = 2147483647
sort_buffer_size = 262144
sql_buffer_result = OFF
