Sorry… I’m not very proficient in Linux. Could you teach me specifically how to set it up?
I’ve never manually changed any system settings. However, I think the hosting provider might be limiting swap because this server appears to be running on HDD (judging by the maximum 2k IOPS).
Can doing these things permanently modify the settings you mentioned?
run：
echo 'sys.kernel.mm.transparent_hugepage.enabled=never' > /etc/sysctl.d/10-huge-pages.conf
echo 'vm.overcommit_memory=1' > /etc/sysctl.d/90-vm_overcommit_memory.conf
and change vm.swapiness = 60 in /etc/sysctl.conf
now: (I’ve reboot after changed all settings. Commands below are run after reboot)

It looks like it’s running well! Thanks you all sincerely for help!
