hi John, I'm curious to see your "Fakespirit" class. At this moment I only need a limit set of commands, so I send by a couple of simple routines to my serial commport driver (indepent thread).

The retry timing for RCX_Link uses a dynamic backoff, which is a good general purpose solution if you're going to be sending lots of packets (like a typical NQC download) and the latency through the serial driver is unknown and/or unpredictable (...)

It has very little to do with C itself - its really a question of compiler optimization. NQC doesn't have any explicit optimization passes, and there is no data flow or variable lifetime analysis, so often the assembly will be a bit inefficient. (...)
