You posted a 7MB size (and an 8MB one), in a post about hypothetical

So that's about 2KB/second of CPU time.

 That is a completely meaningless metric.
 

Are the figures accurate? If you spend an hour of CPU time and the output is a 7MB file, then it /is/ generating 2KB/cpu-second.
On x64, 7MB of instructions (I don't know the machine of the balance of code and data), is very roughly 700Kloc for a language like C. That would make the throughput 200 source lines per cpu-second if it was all C.
Then means it's spending at least 99.9% of the CPU-time doing something other than basic C to native code compilation.
However, you seem happy enough with the process, and don't seem inclined to question it.
