The security gateway appliances from Netgate have been tested and deployed in a wide range of large and small network environments. The following outlines the best practices for choosing the appliance best suitable for your environment. Most features do not factor into hardware sizing, although a few will have a significant impact on hardware utilization:.
Encrypting and decrypting traffic is CPU intensive. The number of connections is much less of a concern than the throughput required.
Captive Portal - While the primary concern is typically throughput, environments with hundreds of simultaneous captive portal users of which there are many will require slightly more CPU power than recommended above. For large environments requiring state tables with several hundred thousand connections, or millions of connections, ensure adequate RAM is available.Post punk bass lines
Packages - Some of the packages increase RAM requirements significantly. The following outlines the minimum hardware requirements for pfSense 2. Note the minimum requirements are not suitable for all environments.
You may be able to get by with less than the minimum, but with less memory you may start swapping to disk, which will dramatically slow down your system.
Selection of network cards NICs is often the single most important performance factor in your setup. A quality NIC can substantially increase system throughput. When using pfSense software to protect your wireless network or segment multiple LAN segments, throughput between interfaces becomes more important than throughput to the WAN interface s. NICs based on Intel chipsets tend to be the best performing and most reliable when used with pfSense software.
Above 1Gbps, other factors, and other NIC vendors dominate performance. The numbers stated in the following sections can be increased slightly for quality NICs, and decreased possibly substantially with low quality NICs. All of the following numbers also assume no packages are installed. Remember if you want to use your pfSense installation to protect your wireless network, or segment multiple LAN segments, throughput between interfaces must be taken into account. In environments where extremely high throughput through several interfaces is required, especially with gigabit interfaces, PCI bus speed must be taken into account.
When using multiple interfaces in the same system, the bandwidth of the PCI bus can easily become a bottleneck. Products Home Products. Buy Now Build Your Own.Apikey dnv error code 246520
Feature Considerations Most features do not factor into hardware sizing, although a few will have a significant impact on hardware utilization: VPN - Heavy use of any of the VPN services included in the pfSense software will increase CPU requirements. Server class hardware with PCI-e network adapters. More Details.Would you like to learn how to configure the Pfsense link aggregation feature?

On the prompt screen, enter the Pfsense Default Password login information.Some users have reported that making the following change has greatly increased performance:. Change kern. See Hardware Tuning and Troubleshooting for more information on that setting.
Some people have also seen better performance by using the ufs cache filesystem setting. When using ufs filesystem, vfs. Squid keeps a cache index journal called swap. This file can grow very large and consume all hard drive space. To ensure this does not happen, set a Log Rotate value in the squid configuration.
By setting a number of days to retain the logs, the squid package will activate a nightly cron job which runs:. Part of this rotation process includes compacting the swap.
If this file is too large and needs to be removed, this may be done while squid is running. After the file is removed, run:. This will cause it to be written out again but compacted. Alternately, tell squid to perform a clean shutdown with:. This will also write the swap. If the swap. This can be a lengthy and time consuming process. It may be better to remove the contents of the existing cache folder, and rebuild the structure again by running:.
See the Squid FAQ entry for more details. There could be any number of reasons not to do the following things. Be careful, and test any changes. Change the Maximum object size to something big, such as for MB.
Going bigger may be needed if any updates larger than that size are released. Otherwise if a user requests a file and then aborts, it will download the whole file. Setting parent proxy available at the Proxy server: Upstream proxy settings tab. In most cases, these settings work if the parent proxy also squid. To use a parent proxy on another server not squidit is necessary to disable Upstream proxy settingsand use the Custom options in the Proxy server: General settings tab. Netgate Logo Netgate Docs.

Now, are there any settings that I can use to improve the speed? I tried running the client from 2 different computers, at the same time.
Both clients got about half of the total speed, and Mbps. Re: CPU loading across the cores, I saw that not all cores were used. I have set most of the settings from that tunning page. The only thing I didn't set was hw. Animosity No traffic shaping. You shouldn't need to set the igb queues to 1 any longer. That was a bug in much older versions. Just hit q in top when it's showing something useful and it will quit out and leave whatever was there available to copy and paste out.
Hi bdaniel7. FreeBSD's network defaults aren't tuned too well for very high speed connections by default although this is getting better in newer versions. Here is a link to a thread with some more parameters you can tune on your Intel NIC's:. I'm only using OpenVPN to access the internal network from outside. Which is happening when I'm at the office. I'm starting top -aSH as you suggested, then during the peak transfer, I exit from top with q.
I disabled powerD but there is no difference. Hi bdaniel7 - have you also tried tuning some of the additional parameters that I suggested?
If yes, what were the results? Sorry I meant where are you testing between? Speedtest client on igb1 connecting to a server via igb0? Ah, then that is the cause of the problem. You can see that all the loading is on one queue and hence one CPU core while the others are mostly idle. However there is something you can do to mitigate it to some extent, set: sysctl net.
Be aware that doing so may negatively impact some other things, ALTQ traffic shaping in particular.
How to fine-tune pfSense 2.4.5 for 1Gbit throughput on APU2/APU3/APU4
Thank you for the clarification.Update : This article has been updated for pfSense 2. It's still possible to get 1Gbit on pfSense 2.N64 emulator chromebook unblocked
It's now possible to get full gigabit throughput when utilizing multiple NIC queues. This article was originally written for pfSense 2. The old instructions available here before this update were for pfSense 2. This made some readers unhappy.
The instructions below are now updated to work on pfSense 2. I don't guarantee that these instructions will work in the future releases, but I'll do my best to update this article every time something changes.
This limitation still exists, however, a single-core performance has considerably improved. These NICs have 4 transmit and four receive queues, being able to work simultaneously on 4 connections. With some fine0tuning, pfSense can take advantage of this and route at 1Gbit when using more than one connection.
This is less performant NIC, but it's still good enough to deliver 1Gbit on pfSense when more one than one connection is used.
Note: the intel PDF specification for IAT has a mistake - it states that there are 4 queues while there are only 2. Routers rarely open just one connection, so a single connecton is rarely a bottleneck in the real world. Web browser opens about 8 TCP connections per website, Torrent clients open hundreds of connections, Netflix opens multiple TCP connections when streaming video, etc.
Note, some users say that TSO and LRO should be disabled, and enabling these settings may actually decrease performance. This is not what we see in our tests. If you have specific information about the conditions under which this is true, please send us an email.
These settings are the change between 2. Now we need to edit some settings from the shell. You can SSH to the box or connect with the serial cable. Now you can run some tests to verify that your settings worked properly. The easiest way is to use iperf3 with multiple connections, where one device is on the LAN and the other one on the internet. I think this is quite neat. Note from the author This article was originally written for pfSense 2.
Make sure that all 3 first checkboxes under "Network Interfaces" are unchecked. Find the following two tunables and set them to 0. If you don't set this, queues won't be utilized properly allow multiple processes to processing incoming traffic hw. TekLager specializes in selling open source hardware for building routersfirewalls and other network appliances.
Qualcomm Atheros AROthers are outlined in the FreeBSD main page tuning 7. The default installation includes a well-rounded set of values tuned for good performance without being overly aggressive.
There are cases where hardware or drivers necessitate changing values or a specific network workload requires changes to perform optimally. The hardware sold in the Netgate Store is tuned further since Netgate has detailed knowledge of the hardware, removing the need to rely on more general assumptions. Intel igb 4 and em 4 Cards. A common problem encountered by users of commodity hardware is mbuf exhaustion. For details on mbufs and monitoring mbuf usage, see Mbuf Clusters.
If the firewall runs out of mbufs, it can lead to a kernel panic and reboot under certain network loads that exhaust all available network memory buffers. In certain cases this condition can also result in expected interfaces not being initialized and made available by the operating system.
This is more common with NICs that use multiple queues or are otherwise optimized for performance over resource usage. Additionally, mbuf usage increases when the firewall is using certain features such as Limiters. That number can be again be doubled or more as needed, but be careful not to exceed available kernel memory.
Some network interfaces may need other similar values raised such as kern. In addition to the graphs mentioned above, check the output of the command netstat -m to verify if any areas are near exhaustion.
For performance reasons some networks cards use multiple queues for processing packets. On multi-core systems, usually a driver will want to use one queue per CPU core. A few cases exist where this can lead to stability problems, which can be resolved by reducing the number of queues used by the NIC. The name of the sysctl OID varies by network card, but it is usually located in the output of sysctl -aunder hw. Message Signaled Interrupts are an alternative to classic style Interrupts for retrieving data from hardware.
Network cards which support multiple queues rely on hashing to assign traffic to a particular queue. This can lead to a network card under performing with the default network settings, as noted on and FreeBSD PR Adding a System Tunable or loader.
Tuning the values of net.Introgresión denisovana también en los euroasiáticos del este y los
Generally these are best left at default values matching the number of CPU cores, but depending on the workload may work better at lower values. There have been no recent reports, however, so it should be safe on current releases.
Ensure the options are checked. Sometimes disabling via sysctl is also necessary. If the above shows values above 0try doubling the current value of net.
