Hi Steve,

On our system, Mariadb 10.1.22, with aria_used_for_temp_tables = ON, we have a set of MyISAM settings carried over from an earlier setup. Those settings are:

key_buffer_size=256M
myisam_sort_buffer_size = 64M
join_buffer_size=512K
bulk_insert_buffer_size=512M
read_rnd_buffer_size = 1M

read_rnd_buffer_size and join_buffer_size are not MyISAM specific settings, did you try to modify/not modify only those ones ?

HTH,

Really? So, the doc is wrong?

Says, MyISAM. So, are you saying that is mistaken? If so, that would make sense
