You got to find you what is your bottleneck. When you are under attack you need to gather as much information as you can and then analyze that. Whether the internet pipe to your server is full or your CPU cracks down.
And secondly: Are you sure that SA-MP is even involved during an attack? Maybe other services running on your server are exploited to down you. For instance you should not run Apache on the same IP as your SA-MP server, Apache has a large attack vector to eat up your resources. Always get a dedicated IP which you only use for SA-MP and configure your webserer (if you have any) to go through Cloudflare and hide it's real IP.
