High Performance Design event - Presented by Nick Zeeb

When economic news comes out, trading volumes spike and the LMAX Exchange needs to push out the latest prices to all of our clients as fast as possible.

This presentation is about how we solved this problem by using Test Driven Design.  It will show, step by step, how we created a lock-free, high performance data structure by using knowledge of how modern processors are designed.

Who Should Attend:

Anyone interested in writing high performance code. This talk covers the entire design story starting from how we approached the problem, all the way down to the low-level code tweaks to squeeze out the last drop of performance.


Nick Zeeb is a core Java developer at LMAX Exchange in London. LMAX operates a financial exchange that is capable of handling 20,000 orders per second with a mean latency of 1.5 milliseconds.

Nick has been involved in the financial industry since 2006 and has seen some interesting times while working at a hedge fund, an investment bank and now an exchange

    It was a great talk on a sound piece of software.
    Just out of curiosit, has anyone benchmarked LMAX collections with Goldman Sachs collections? There was a meeting last week about these latter ones, which I could not attend unfortunately, but they sound both awesome and pretty similar...

      Thanks, the LMAX Collections Project only includes the Coalescing Ring Buffer at this point but we are planning on adding more to the project. At that point we'll definitely want to benchmark them against what other people are doing.

    Really interesting and real world presentation! Hopefully it will be made available afterwards to study the code snippets further!

    With all these talks around LMAX in the last couple of years, one would thing they are the only ones innovating around here... :) Anyhow good to them for taking the time and spending the effort...

      @robo most financial tech is very secretive, they believe that their business advantage is tied to keeping discussions about their technology stack secret...
      it's a breath of fresh air to have a company in that sector open to conversations about it =)

      Hi Chris, thank you for your reply... You're maybe right, I don't have the statistics... we do some funky stuff in the financial company I work for, but to be honest the reason we don't advertise it, is much more mundane than secrecy... it's simply lack of time or will from the management side to invest in this kind of activity. LMAX went beyond being open, they've become evangelical about their technology... I'm not saying it's bad, I appreciate their efforts, it's just ever so slightly annoying to not see anything else around, just the all pervasive Disruptor in every single conference around... I even went to a MongoDB workshop at QCon, just to have Trisha mention LMAX several times and hand us the driver code on LMAX branded memory sticks ! :) Anyhow, I'm sure the talk will be great !
