Thanks: Compiling to C speeds it up a bit more.

comment Why is Poisson Random Deviate Generation so slow?
@ybeltukov You did a great job, but I need a fast Poisson for any m vector that includes positive numbers. I am not interested, particularly, in using those that are generated from a Uniform distribution.

@ybeltukov This is good, but I used the uniform just to have different Poisson rate parameters on each draw of the Poisson. I am not interested in a mixture of a poisson and the uniform.

I think it relies on the Rmath standalone c library that underlies the distribution functionality of the R statistical language.

I am aware that parallelization can speed up things. But still, even after this, it is too slow, in the context of numerical work involving thousands of iterations. It would be great if the function could be compiled, at least.

comment Why LibraryLink function crashes at a second time?
@rubenko: Yes, a top level interface would be great as the built in Mathematica functions for linearsolve and inverse are not compilable

Thanks for this. I am not sure whether double MTensorVector_getReal(MTensor t, mint pos) really exists. Will wait a bit before accepting.
