Berikut adalan tuning kerneldi  Ubuntu agar tambah jozz
# cp /etc/sysctl.conf /etc/sysctl.conf.bak
# Vi /etc/sysctl.conf

ganti semua isinnya dengan ini

code :

kernel.core_uses_pid=1
kernel.sysrq=1
net.core.optmem_max=28672
net.core.rmem_max=1280000
net.ipv4.tcp_rmem=4096 87380 1280000
net.core.wmem_max=1280000
net.ipv4.tcp_wmem=4096 87380 1280000
net.ipv4.conf.default.rp_filter=1
net.ipv4.conf.all.rp_filter=1
net.ipv4.conf.all.log_martians=0
net.ipv4.conf.all.accept_source_route=0
net.ipv4.conf.all.accept_redirects=0
net.ipv4.tcp_max_tw_buckets=720000
net.ipv4.tcp_window_scaling=0
net.ipv4.tcp_keepalive_time=1200
net.ipv4.tcp_timestamps=0
net.ipv4.tcp_fin_timeout=15
net.ipv4.tcp_sack=0
net.ipv4.tcp_syncookies=1
net.ipv4.icmp_echo_ignore_all=1
net.ipv4.icmp_echo_ignore_broadcasts=1
net.ipv4.icmp_ignore_bogus_error_responses=1
net.ipv4.ip_local_port_range=1024 65535
net.ipv4.ip_forward=1
net.ipv4.ip_dynaddr=0

setelah itu save dan keluar
:wq
#sysctl -p
#reboot
