R80.x Performance Tuning Tip – Multi Queue

What is Multi Queue?

 

It is an acceleration feature that lets you assign more than one packet queue and CPU to an interface.

When most of the traffic is accelerated by the SecureXL, the CPU load from the CoreXL SND instances can be very high, while the CPU load from the CoreXL FW instances can be very low. This is an inefficient utilization of CPU capacity.

By default, the number of CPU cores allocated to CoreXL SND instances is limited by the number of network interfaces that handle the traffic. Because each interface has one traffic queue, only one CPU core can handle each traffic queue at a time. This means that each CoreXL SND instance can use only one CPU core at a time for each network interface.

Check Point Multi-Queue lets you configure more than one traffic queue for each network interface. For each interface, you can use more than one CPU core (that runs CoreXL SND) for traffic acceleration. This balances the load efficiently between the CPU cores that run the CoreXL SND instances and the CPU cores that run CoreXL FW instances.

Important - Multi-Queue applies only if SecureXL is enabled.

Multi-Queue Requirements and Limitations

Tip 1

  • Multi-Queue is not supported on computers with one CPU core.
  • Network interfaces must use the driver that supports Multi-Queue. Only network cards that use the igb (1Gb), ixgbe (10Gb), i40e (40Gb), or mlx5_core (40Gb) drivers support the Multi-Queue.
  • You can configure a maximum of five interfaces with Multi-Queue.
  • You must reboot the Security Gateway after all changes in the Multi-Queue configuration.
  •       For best performance, it is not recommended to assign both SND and a CoreXL FW instance to the same CPU core.
  • Do not change the IRQ affinity of queues manually. Changing the IRQ affinity of the queues manually can adversely affect performance.
  • Multi-Queue is relevant only if SecureXL and CoreXL is enabled.
  • Do not change the IRQ affinity of queues manually. Changing the IRQ affinity of the queues manually can adversely affect performance.
  • You cannot use the “sim affinity” or the  “fw ctl affinity” commands to change and query the IRQ affinity of the Multi-Queue interfaces.
  • The number of queues is limited by the number of CPU cores and the type of interface driver:

i40e

  •      The maximum RX queues limit dictates the largest number of SND/IRQ instances that can empty packet buffers for an individual interface using that driver that has Multi-Queue enabled. 
  • Multi-Queue does not work on 3200 / 5000 / 15000 / 23000 appliances in the following scenario (sk114625)
  • The number of traffic queues is limited by the number of CPU cores and the type of network interface card driver.
    The on-board interfaces on these appliances use the igb driver, which supports up to 4 RX queues.
    However, the I211 controller on these on-board interfaces supports only up to 2 RX queues.
When Multi-Queue will not help

Tip 2

  • When most of the processing is done in CoreXL - either in the Medium path, or in the Firewall path (Slow path).
  • All current CoreXL FW instances are highly loaded, so there are no CPU cores that can be reassigned to SecureXL.
  • When IPS, or other deep inspection Software Blades are heavily used.
  • When all network interface cards are processing the same amount of traffic.
  • When all CPU cores that are currently used by SecureXL are congested.
  • When trying to increase traffic session rate.
  • When there is not enough diversity of traffic flows. In the extreme case of a single flow, for example, traffic will be handled only by a single CPU core. (Clarification: The more traffic is passing to/from different ports/IP addresses, the more you benefit from Multi-Queue. If there is a single traffic flow from a single Client to a single Server, then Multi-Queue will not help.)
Multi-Queue is recommended
  • Load on CPU cores that run as SND is high (idle < 20%).
  • Load on CPU cores that run CoreXL FW instances is low (idle > 50%).
  • There are no CPU cores left to be assigned to the SND by changing interface affinity.

Notes to Intel igb and ixgbe driver

I used the LKDDb Database to identify the drivers. LKDDb is an attempt to build a comprensive database of hardware and protocols know by Linux kernels. The driver database includes numeric identifiers of hardware, the kernel configuration menu needed to build the driver and the driver filename. The database is build automagically from kernel sources, so it is very easy to have always the database updated. This was the basis of the cross-reverence between Check Point HCL and Intel drivers.

Link to LKDDb web database:
https://cateee.net/lkddb/web-lkddb/

Link to LKDDb database driver:

igb, ixgbe, i40e, mlx5_core    

Here you can find the following output for all drivers e.g. igb:

Numeric ID (from LKDDb) and names (from pci.ids) of recognized devices:

  • vendor: 8086 ("Intel Corporation"), device: 0438 ("DH8900CC Series Gigabit Network Connection")
  • vendor: 8086 ("Intel Corporation"), device: 10a9 ("82575EB Gigabit Backplane Connection")
  • vendor: 8086 ("Intel Corporation"), device: 10c9 ("82576 Gigabit Network Connection")
  • vendor: 8086 ("Intel Corporation"), device: 10d6 ("82575GB Gigabit Network Connection")

and many more...

How to recognize the driver

With the ethtool you can display the version and type of the driver. For example for the interface eth0.

# ethtool -i eth0

driver: igb
version: 2.1.0-k2
firmware-version: 3.2-9
bus-info: 0000:02:00.0

Active RX multi queues - formula

By default, Security Gateway calculates the number of active RX queues based on this formula:

RX queues = [Total Number of CPU cores] - [Number of CoreXL FW instances]

Configure

Hi Dameon,

this was not planned. Smiley Happy

As I said I once referenced all network cards for 3 hours between Check Point HCL and Intel.

After that I wrote this article. I will complete and revise the article in the next few days.

Here is the link to the original discussion:

Re: R80.x Performance Tuning Tip – Multi Queue

I noticed the following. The following drivers and network cards are not yet supported by Check Ponit Open Server HCL.

Is there a reason that 40Gbit/s network cards are not yet present in the HCL?

I think from a performance point of view, an open server with MQ should also be able to handle that.

What are the reasons why that are not supported?

Actual NICs supported by this driver i40e version according to Intel:

Re: R80.x Performance Tuning Tip – Multi Queue

Hi Heiko Ankenbrand,

First of all!  Thank you very much for the information.

But I have one more question! How did you cross-reference the network cards?

What sources did you use?

Regards

Harry

Re: R80.x Performance Tuning Tip – Multi Queue

Important clarification

We appreciate Heiko Ankenbrand‌'s article on multi-queue and research. However, some points need to be mentioned:

  1. The list above is not an official reference from Check Point Software Technologies
  2. When choosing an Open Server and NICs for it, always consult with HCL: Compatible Hardware Archive | Check Point Software and make sure a combination of Open Server platform and network cards you are going to use is mentioned for your specific software version as supported
  3. As we are constantly expanding multi-queue support, consult with the software release notes and relevant SK articles before enabling the feature.
  4. In case of any doubt we encourage you to consult Check Point software Technolgies through official channes: TAC and/or your local CP office.

Once more, thanks to the author for his contribution to this community. Keep up the good work.

Re: R80.x Performance Tuning Tip – Multi Queue

Here I agree with Valeri Loukine. You should always look at the HCL and relevant SK's, readme and documentation. I was just trying to reference the HCL to the network card drivers. 

Thank you Valeri, I have included the following in the article.

CUT>>>

The list is cross-referenced to the Intel drivers. I do not assume any liability for the correctness of the information. These lists should only be used to help you find the right drivers. It is not an official document of Check Point!

 

So please always read the official documents of Check Point.

Re: R80.x Performance Tuning Tip – Multi Queue

That would seem to be the case based on your ethtool output, but based on my very negative experiences in the past with Broadcom NICs I wouldn't trust them to carry any production traffic whatsoever, let alone a heavy volume of traffic that would require use of Multi-Queue.  No thanks.

Re: R80.x Performance Tuning Tip – Multi Queue

Please note that I don't suggest anyone to use Broadcom adapters and my post was only for an informative purpose, because this is the only good article on the Internet where people can get information on multi-queue supported devices and drivers. It would be good if people shared some information about different NIC's not described here.

Today I have tested the mlx5_core driver with Mellanox MCX4121A-XCAT ConnectX-4 Lx EN (dual 10G) and turns out it supports more than 10 RX queues, stated as 'Maximal number of RX queues' in this article:

Re: R80.x Performance Tuning Tip – Multi Queue

Quick question,

are all appliance ports compatible with multi queueing?

Re: R80.x Performance Tuning Tip – Multi Queue

Generally yes as long as it is an adapter using a supported driver (determined with ethtool -i (interface)).  Supported drivers are:

Intel: igb (4 queues maximum), ixgbe (16 queues maximum) & i40e (48 queues maximum)

Mellanox: mlx5_core (Gaia 2.6.18 - 10 queues maximum, Gaia 3.10 - 48 queues maximum), mlx_compat (Gaia 2.6.18 - 10 queues maximum, Gaia 3.10 - 48 queues maximum)

Note that the driver (and possibly kernel version) will usually limit the maximum number of queues per interface, but there are some exceptions such as the onboard I211 interfaces that use the igb driver, yet the NIC hardware only supports 2 queues.  See sk114625 for more details.

The limit of no more than 5 interfaces that can have Multi-Queue enabled simultaneously is a Gaia 2.6.18 kernel limitation, and has been lifted in Gaia 3.10.

There have also been some observations that newer Broadcom adapters (which are used on some open hardware firewalls) appear to support Multi-Queue, but I wouldn't trust Broadcom NIC hardware to perform even the most basic function (such as being violently smashed with a hammer) with any degree of stability or competence, let alone implement a feature like Multi-Queue.
