I was able to rebuild my prototype completely in Node.js and with this version I’m able to run it on AIX at full speed. So, with a pure Node.js stack I can see absolute no performance issues at all.
And as soon as I use a Java client or a Java Webservice together with Node I hit the performance problem. I don’t have the Java sources available but have already send a request to the developer to check if he has set the tcp socket option TCP_NODELAY=true. I suppose there is a timing issue on the tcp socket connections in Java, that’s a typical problem when doing a lot of current socket connections with a few 100 per second, then the old style NAGLE features hits you like a hammer with a delay of up to 200ms on each connection. After all, now I’m sure there is no performance problem with Node.js on AIX! Sorry for any confusion.
