Hello,
I am using mikrotik hotspot with 120 users..my problem is that when 50 users or above are connected to my hotspot my cup load increases to 100 % !!
i am using mikrotik router os 5.20 X86
my system requirement is
dell precision 650
1gb ram
3.2 x 2 processor
kindly see the attached screenshots !
This may be unrelated but do you have SSTP enabled?
We had an issue with SSTP on that build a while back. Simply disabling it or upgrading to ROS5.22 or above fixed it.
