Compile time shortens exponentially with increased memory

Well, it did not take me too long to work out how to do something useful with R and, indeed, get a really interesting result (see graph below):

Linux compile timesThere are a fair few missing data points here – experiments take time – but already you can see that there appears to be a fairly clear relationship between the time it takes to compile a Linux kernel and the available memory as shown by what looks like an exponential shortening of compile times as memory increases.
