Used it experimentally to port a python tool that does some log aggregation with several options (read backwards, query on fields, etc) and returns the results in JSON. A straight line by line port (ie less idiomatic Go) runs at about twice the speed of Python and with the same memory footprint. With the right fine tuning should be even better. It was also very easy to do -- i.e code translated quite easily from Python to Go.
