We see that using the compiled model is by a factor of 13.6 faster than using the R version with the default ode solver, and it is even faster than the Eigenvalue based solution implemented in R which does not need iterative solution of the ODEs:

Here we get a performance benefit of a factor of 14.9 using the version of the differential equation model compiled from C code!
