[Ubuntu] Starting HLDS with a higher priority

Hello Guys!
I've been using Ubuntu 16.04 LTS for my HLDS server for the past 2 years. The server wasn't famous so with the amount of plugins it ran fine but now it's famous lot of people come so the fps were quite unstable so I upgraded the machine from the VPS hosting and saw that the same thing happened. So I followed a few guides and compiled a kernel with some custom settings, changing the process's priority and it's scheduling policy I saw that the server ran quite stable but the server starts by a startup script and I don't have time to change the process's priority and scheduling policy everytime. Is there anyway that I can make it start at a higher priority + the scheduling policy?

The commands I've been using are:

The Schedule policy cmd:

Code:

chrt -p -r 99 pid

Renice:

Code:

renice -20 pid

I've heard of the task set command anyway to do it?

Startup script:

Code:

cd /home/steam/Steam/cs/&&screen -A -m -d -S server ./hlds_run -game cstrike -ip 35.154.172.22 +port 27015 +map de_dust2 +maxplayers 32 -exec server.cfg -pingboost 2 +fps_max 1100 -condebug

Re: [Ubuntu] Starting HLDS with a higher priority

change the startup script to :

PHP Code:


		
			
cd /home/steam/Steam/cs/&&screen -A -m -d -S server nice -n -20 chrt -r 90 ./hlds_run -game cstrike -ip 35.154.172.22 +port 27015 +map de_dust2 +maxplayers 32 -exec server.cfg -pingboost 2 +fps_max 1100 -condebug

Thank you but the server doesn't even start. I can't even see the screen process.

The script is started by root only. I use the default /etc/rc.local script and have added the line to start the server.

Running any process that is open to the internet as root is risky. If you are only doing it for a personal LAN situation, it won't matter.

Thanks for your response. What I did was make an executable named server and added this line:

PHP Code:


		
			
chrt -r 99 nice -n -20 ./hlds_run -game cstrike -ip 35.154.172.22 +port 27015 +map de_dust2 +maxplayers 32 -exec server.cfg -pingboost 2 +fps_max 1100 -condebug

and I just changed the startup in /etc/rc.local to:

PHP Code:


		
			
cd /home/steam/Steam/cs/&& screen -A -m -d -S server ./server

Now it starts with the highest priority (-20) and it's scheduling policy is RealTime
