Slow Throughput after installing v18 EAP

Hi,

I upgraded from v17.5.8 to v18 EAP about a week ago and noticed a drop in performance and an increased RAM usage.

I do have a XG115 rev2 Appliance installed with the Software  Image and a Home Use License.

My Internet connection is 100/40.

With version 17.5.8 I was able to reach about 80 to 90 Mbit download (I already expected more from the hardware)

After the Upgrade I only reach about 50 to 60 Mbit download. There is no DPI or webfiltering activated and it doesn't matter if i activate IPS or not.

SSL/TLS Inspection is turned on but there are not any rules.

Are there any tweaking options for the software version of Sophos XG running on a HW Appliance?

Thank you!

  • I think ram usage is going to stay about the same due to additional DPI engine. They are not supporting appliances less that 4GB. I even tried installing a vm with less that 4GB and the installation fails. Even after installation, if you try to decrease the ram in a vm, the firewall goes to safe mode if the ram gets below 3600MB.

    I also found that the load average is considerably higher compared to v17.xx Compare you old load average graphs and there is definitely an uptick.
