Slow Performanced Based on Order of ACL Rules

We have several PAN 3020s at a client site with similar issues but for this, I’ll focus on a specific case. One pair in Active\Passive HA has 124 rules. We started noticing really slow RDP connect performance. (it would take 45 seconds to establish an RDP session to a target where the traffic was passed through the firewall). Out of the 124 rules, the rule which this RDP traffic matched on was around rule 100. If we moved that rule up earlier in the ACL to say, rule 5, the RDP session would only take 10 seconds or less to establish.

So initially, it is looking like the further down the ACL the rule is, the longer it takes the PAN to process that traffic. However, seeing that the 3020 supports up to 2500 policies and we only have 124, I wanted to check with you as it doesn’t seem right.

We are not doing any PBF here. Or App-ID override. Jumbo frames are enabled.

Hello mackwage,

Would it be possible for you to take a packet capture for this traffic in both "receive" and "Transmit" stage. Then we can compare the processing time between receive and transmit in both conditions ( Rule at 5 and rule at 100).

What is the Data-plane utilization on this firewall including packet-rate, total active sessions, H/W nd S/W buffer, packet-descriptor, DP-CPU etc..?

Thanks

Thanks for the reply! We can work on getting pcaps.

For the dataplane utilization, I am not sure where to get ALL of that info.

In the WebGUI, I can see the DP-CPU ranges between 2-6%. We ran show system statistics session and got.

The average throughput was 400-800k.

The sessions were ~900.

Hi Mack,

Firewall is under utilized, hence its not over utilization issue. You are right, you can view MP/DP CPU on Dashboard.

Please provide us following output.

debug data-plane pool statistics

show system statistics session

show running resource-monitor

show session info

show counter global filter delta yes  ( repeat the same command 5 times)

PCAP along with the resource utilization would give us more insight about this issue.

Thanks

I would take a look at the rules and organization.  One of the things I've seen that can affect initial session setup time is the number of rules that are application only with the "any" port selection.

These rules should always be towards the bottom of the rule base.

The most specific rules with specified ports and applications should be at the top.

What happens with application and any rules is that PanOS essentially holds on that rule while the traffic is coming through and makes sure that the application is not a match before moving on to the next rule for checks.  If there are a number of these "any" port rules each one does the check and passes on and the time delay can add up.

Thanks for your input!

In this firewall, we do not have any rules which have an application specified along with service ANY. We do however have several rules which list an application with service "application-default". Is it faster processing wise to explicitly list the port as oppose to app default?

Hello Mackwage,

Output looks good, no issue. Would it be possible to provide packet captures.
