mysql (mariadb) 튜닝 및 성능 테스터

mysql (mariadb) 튜닝 및 성능 테스터

my.cnf config 파일을 편집하여 mysql(mariadb) 서버에 가장 적합한 성능을 내는 방법을 잘 모르겠습니다.샘플 my-hug.ini를 기준으로 값을 변경했습니다.이것은 제 서버에 대한 최선의 선택이 아니라고 생각합니다.

구성:

• 인텔 Xeon CPU 3.00GHz(+하이퍼 쓰레드) 2배
• 4GB RAM
• 2x scsi HDD 300gb(미러)

애플리케이션이 최고의 성능을 발휘할 수 있기 때문에 My ISAM을 선호합니다.mysql을 실행하기 위한 서버를 기반으로 해서 정말 좋게 만들고 싶습니다 :) 쿼리 통계: 65% 선택, 30% 업데이트

누가 나에게 정말 좋은 구성을 추천해 줄 수 있습니까?서버에서 벤치마크를 만들고 변경해야 할 옵션을 제안할 수 있는 방법이나 소프트웨어가 있습니까?

# The MySQL database server configuration file.

# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
# 
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.

# For explanations see
