Java Communications Faster than C++
Presented by Guillermo L. Taboada (approx 1 hour excl Q&A)

All Java communications rely on TCP/IP, trading off portability in exchange for performance. But performance, both low latency and throughput, is key in the actual context of exponential increase in the amount of network-based computational resources, distributed applications, massive online services and enormous amounts of data. This talk will cover several efforts carried out during the last years in optimizing Java communications, which have succeeded in overtaking even natively-compiled applications (C++). People concerned about the efficiency, performance and scalability of Java distributed applications will enjoy joining the discussion.

Subjects covered: 

The subjects covered:

- Java IO/NIO Sockets as baseline Java communications

- Java Fast Sockets

- Alternatives to native TCP/IP stack.

- Java on Low-latency networks (10/40 Gig. Ethernet and InfiniBand) 

- Impact of Java communications performance on popular middleware (JMS, ZeroMQ/jeroMQ, Hazelcast, Oracle Coherence, Cassandra, HBase)

PPT presentation as well as running live test cases

Who shoud attend:

Performance-concerned developers, system administrators and project leaders which deal with low-latency and high-throughput issues.


Guillermo L. Taboada, PhD ( He has been doing research in high performance communications in Java for the last 10 years, leading a bunch of projects such as Java Fast Sockets and FastMPJ (the fastests sockets and MPI Java implementations). He is CEO and Co-founder of Torus Software Solutions, a company which helps you to accelerate your most critical Java applications. References of Guillermo's projects are his works for HP, Amazon WS, NASA, ESA and the FSI of the City.

    Informative session by Guillermo.
    Tried to install JFS on my MacBook, failed because of the dependency on .so library.
    Am I missing something? Too tired right now to think straight. Need to install Linux on my desktop to try this out.

      Hi Amitoj, JFS is only available on Linux, let me know about your issue at [masked]. We can also give you access to a linux box for you to try.

    Peter Lawrey will present a lightning talk, on the evening, about 100 nano-second ipc messaging in jva.

      Hi Peter, I have only just spotted your comment sorry about that! With regards to speaking - did you mean at this event? as a lightning talk? if so that would be brilliant. Can you email me at [masked] with a title. Many thanks, Anj
