I'd have to dig in and see data to be convinced it's the GC 
making the latency worse than the C implementation, but from what 
I know you've got more experience with this so who knows :)

Doing this on a real network was waaay more work than I was 
willing to put up with for something a colleague said during 
lunch break, so it was done on localhost. The h/w is a Core i7 
Lenovo laptop (W530) with 8GB of RAM running Arch Linux. My 
server code can be found at https://github.com/atilaneves/mqtt, 
the C implementation has its own website: http://mosquitto.org/.
