Why awarrenthttp process is using 99% CPU and the Internet access is very slow with XG 450 over 1Gb/s link ?

lukg

At a peak time awarrenthttp process is using 99% of CPU, load is high above 8-9 and the Internet Access is slow over 1Gb/s link with up to 600-700 live users.  

During the peak time link usage is around 200-300Mb/s or less.

The avd scanning is set to Avira real time and has 1MB limit but still awarrenthttp can go to 99% at peak times.

I have tried with DoS on/off, reducing the number of IPS and application filtering to reasonable minimum and have found little difference.

 

The support case has been opened since mid-December 2016 and no resolution has been provided.

 

Maybe someone in the community has an answer ?

    We are on the latest firmware XG450 (SFOS 16.05.5 MR-5) and the awarrenhttp process is still using lots of CPU and the Internet access is slow or unresponsive at peak times.

    Switching off IPS and Application logging helps a little bit. The screenshot was taken with 550 concurrent users.
