Benchmarking the Mikrotik Routerboard RB1100

I attended and gave a talk at the recent Irish Wireless Conf & Expo on behalf of INEX. I don’t get to do much with wireless links and as such I found many of the talks and exhibitors very interesting. One company that had a large presence through both Wireless Connect in Dublin and Irish Wireless in Shannon was Mikrotik – a company manufacturing routers built on Linux and some kit that I had been meaning to look at for some time.

Following the conference I picked up some RB750’s and RB750G’s and was very impressed. So much so, that I picked up a RB1100 also. The RB1100 specifications include:

  • 13 individual 1Gbps ports;
  • 2 x 5 port switch groups;
  • 800MHz Power PC MPC8544E processor;
  • SODIMM RAM slot with up to 1.5GB RAM;
  • 1 x microSD card slot;
  • 1U rack mount case.

I decided to benchmark this to see at just what rate it could route packets.

Benchmark Methodology and Tests

I used two PCs running Linux with iperf to measure TCP throughout with different packet sizes. To establish a baseline, I ran the same tests with the two PCs directly connected (this is the Direct Connection results below). The maximum achievable result with this is 1Gbps.

An example command line for the test which runs for 10 secs by default and for a packet size of 64 bytes is:

Then I ran four test sets routing traffic between two networks as follows:

  1. No c/t, no f/w: connection tracking disabled and firewall set to allow all;
  2. No c/t, f/w: connection tracking disabled but with some simple firewall rules;
  3. C/t, no f/w: connection tracking enabled but firewall set to allow all;
  4. C/t, f/w: connection tracking enabled and stateful firewall rules.

In addition, I ran the above four tests with the RB1100 configured as a OpenVPN server:

One of the PCs was connected to the RB1100 as a VPN client pushing traffic to the other server on a non-VPN connect with all traffic routed through the RB1100. I also did a baseline test by running the VPN server with the same encryption on one of the PCs with a direct connect to the other and then pushing traffic over the VPN link.


The results can be seen in the following graph:

Without connection tracking and firewall, full line rate is achievable for packet sizes of 256bytes and higher – all in all, an excellent result. That said, no connection tracking and no firewall would be an unusual configuration and with these, the box maxes out at around 525Mbps – still an excellent result for less than €400.

The VPN tests yielded:

VPN throughput primarily relies on CPU horse power and the PCs used for the Direct Connection baseline test are pretty modern.

World IPv6 Day – Do Something – Anything!

June 8th, 2011 is World IPv6 Day and on that day, GoogleFacebookYahoo!Akamai and Limelight Networkswill be amongst some of the major organisations that will offer their content over IPv6 for a 24-hour “test flight”.

I’m trying to push June 8th as a ‘flag day’ for smaller companies to get something – anything – done with IPv6. Enabling AAAA on their websites (and leaving it on) would be super. Some other suggestions I have:

  1. Register on and add the badge to your site. Even if it’s Pending IPv6, the whole point of the project is to nudge the level of awareness up a notch and we need badges on sites for that.
  2. If you haven’t even used IPv6 before, get a SixXS tunnel and be sure to choose either HEAnetAirwire or Digiweb as your tunnel broker. All are members of INEX with good IPv6 connectivity so you’ll see low latency with good connectivity on these.
  3. If you want to get IPv6 on your LAN and your ISP won’t provide it, then (a) bug them some more; and (b) as a intermediate measure, also get a subnet from SixXS for your LAN.
  4. Dual stack your mail server and add a AAAA record to your MX hosts. This is a really simple and painless first step as SMTP is such a resilient protocol, if the mail cannot be delivered over v6, it’ll fall back to v4. Postfix, Sendmail and others have been IPv6 capable for years.
  5. Dual stack your DNS server. Like Postfix / Sendmail, Bind has been IPv6 capable for years. Get it listening on v6 and then add AAAA records to at least one of them.
  6. Hurricane Electric have a very useful IPv6 Certification program (see it at which certifies an individuals ability. It’s a free process and what’s great about it is that, even if not interested in the cert, working through the process gets you configuring IPv6 on your web server, email server and DNS.
  7. Always look for IPv6 when choosing an ISP, a hosting provider, equipment vendors, and SaaS. Even if not a deciding factor, ask for IPv6 support to keep nudging it up the list of priorities for service providers.
  8. Register and display a badge from Did I say that already?


We’re IPv6 Ready! Are you?

IPv6 ReadyOver in INEX, we just launched a new initiative to promote and increase awareness of IPv6 among content owners and businesses generating revenue from an online presence.

This project is called IPv6 Ready and it is essential a certification program for websites that are IPv6 ready to one of two standards:

Gold: The website has a AAAA (IPv6) DNS record; and

Platinum: At least one of the websites DNS name servers is additionally IPv6 enabled.

IPv6 PendingFor those websites that are not IPv6 enabled (and in many cases this is dependent on a third party hosting company), we also have a very cool IPv6 Pending badge which you can use to let your customers know that you are IPv6 aware.

The badges shown here are the large versions but we also have an extra large, medium and small so you’ll find an appropriate one for your site.

How do you get your badges? Easy, just head over to and register your site. Once you complete the simple process, you’ll be emailed all four personalised badges!

Help us make this a success! Please repost, blog, tweet and spread the word any way you can to help us raise awareness and push IPv6 forward – even just a little. If nothing else, please register and display a badge! You’ll also get a link such as this to your own certificate!

It’s Official, I’m Not the Only Political Anorak in Ireland

INEX, Ireland’s Neutral Internet Exchange Point, saw a new Irish Internet traffic record of just under 14Gbps today coinciding with both Enda Kenny’s nomination and the announcement of the new ministers.

It’s nice to know I’m not the only anorak!

INEX Breaks 10Gbps Barrier – Again

INEX, Ireland’s Neutral Internet Exchange Point, broke the 10Gbps barrier last week coinciding with the Government’s budget announcement. It didn’t quite break the previous record from the announcement of the four year plan.

This traffic spike would have been primarily driven by HEAnet and RTE streaming the Dáil proceedings live to Irish Internet viewers – INEX’s members would account for about 97% of all eyeballs in Ireland.

INEX makes its overall traffic statistics publically accessible.
