-------- Recommendations -----------------------------------------------------
General recommendations:
Run OPTIMIZE TABLE to defragment tables for better performance
MySQL started within last 24 hours - recommendations may be inaccurate
Variables to adjust:
*** MySQLs maximum memory usage is dangerously high ***
*** Add RAM before increasing MySQL buffer variables ***
sort_buffer_size (> 4M)
read_rnd_buffer_size (> 4M)
yo solo tengo instalados 3gb, pero me aparece que el maximo permitido es 3.7, en que parte puedo modifcar o editar ese valor de 3.7gb y en cuanto me recomiendan dejarlo. espero me puedan ayudar. saludos
