[erlang-questions] Optimising TCP/IP connectivity

Hi Oscar,Very interesting reading! I wish I had known you were working on this. I have been experimenting with an information push system using ejabberd, where the profile is a low traffic (with bursts) but lots of connections. Can you expand on the problems with FreeBSD? Even if outside the scope of the paper, did you investigate it? Hilsen,AndersOscar Hellström wrote:
Hi All,I've just finished my bachelor thesis titled "Optimising TCP/IP connectivity: An exploratory study in network-intensive Erlang systems".A number of operating systems, VM-options and TCP stack optimisations have been evaluated to be able to maintain as many concurrent connections as possible.The thesis can be found is online at http://www.erlang-consulting.com/aboutus/erlangarticles.htmlThe paper describes a series of benchmarks on a popular network-intense Erlang application. During these benchmarks asynchronous threads, kernel poll and TCP Window Sizes has been evaluated. The same benchmarks has also been run on several operating systems, on the exact same hardware. There are some interesting differences, both between he operating systems and within the same operating system but with other parameters used to start Erlang.Best Regards
