The paper / slides on Optimising TCP/IP connectivity in network 
intensive Erlang systems are already online.



*Abstract:* With the increased Use of network enabled applications and 
server hosted software systems, scalability with respect to network 
connectivity is becoming an increasingly important subject. The 
programming language Erlang has previously been shown to be a suitable 
choice for creating highly available, scalable and robust telecoms 
systems. In this exploratory study we want to investigate how to 
optimise an Erlang system for maximum TCP/IP connectivity in terms of 
operating system, tuning of the operating system TCP stack and tuning of 
the Erlang Runtime System. The study shows how a series of benchmarks 
are used to evaluate the impact of these factors and how to evaluate the 
best settings for deploying and configuring an Erlang application. We 
conclude that the choice of operating system and the use of kernel poll 
both have a major impact on the scalability of the benchmarked systems.

The paper and slides on priority messaging and the presentation on 
comparing Erlang and C++ from CUFP will be put online tomorrow.
