i have question about waiting for HDD. I'm not sure what is optimal %wa.
Server running browser game, i know that there is a lot hdd writing but im not sure what is optimal %wa. Server running 8 cores processor with 16gb of RAM. Mysql uses 20-35% CPU, and running 3 MySql databases.
%wa is 5-15% when 150 players are online. Is that ok or i didn't configured mysql, php or something other ok?
