Slow webpage Load times

L3 Networker

Have two Firewalls setup in azure with LB on the trust interface side and no LB on the untrust side. I am experiencing slow web page load times. Sometimes it doesnt even load or loads parts of the page. Any ideas what could be causing this?

Did you test dissabling SSL decryption for the page as VM machines are not good with this?



Also did you check the VM for HIGH CPU or memory?



Also I had simiar issue "I have seen for example on a small firewall when the customer enables SSL decryption that the counters for work groups "ecdhe_key_gen", "flow_host " etc. jump. This may show that the firewall can't handle the ssl decryption or that there is an SSL DDOS attack".

Also just in case check your DOS logs as the DOS profile and Zone protection profile could cause such issues in rare cases:



Check just in case this article and check if the Azure LB is redistibuting correcly the traffic between the firewalls:


Cannot get SSL decrypt to work on Azure with AZ App Gateway




And just in case see the URL filtering logs but as page loads sometimes I do not think the issue is there:

I forgot to add that you can use the new palo alto AIOps feature to check the firewall. The feature supports streaming data to the Palo Alto cloud or uploading tech support file:
