리눅스 튜닝 값 - 부하테스트 진행 하는 경우

부하테스트를 진행하는 중 서버에 튜닝을 해서 최적화를 해야 하죠!

부하발생기에서도 부하를 유입하기 위해서는 이 클라이언트도 튜닝을 해야 합니다.

 

리눅스 서버의 경우 , 아래 내용으로 셋팅을 다시 해야 충분히 부하발생기에서도 부하를 유지 할 수 있습니다.

 

 

# sysctl settings are defined through files in

# /usr/lib/sysctl.d/, /run/sysctl.d/, and /etc/sysctl.d/.

#

# Vendors settings live in /usr/lib/sysctl.d/.

# To override a whole file, create a new file with the same in

# /etc/sysctl.d/ and put new settings there. To override

# only specific settings, add a file with a lexically later

# name in /etc/sysctl.d/ and put new settings there.

#

# For more information, see sysctl.conf(5) and sysctl.d(5).
