Performance

[majurgens]

Hi - I am the author of check wmi plus.

One of the things with the existing wmic binary is that you need to fork it each time you run it. This is performance overhead that can be a big problem on some production monitoring implementations. From what I have seen of python, it is very slow to fork a new process, much slower than a compiled binary.

One suggestion that I would make is to have an operation mode of your wmic replacement that allows you to have a long running python service where check wmi plus can simply make some form of API call, hence totally avoiding the forking overhead. Perhaps some kind of REST interface that perl can call using LWP or something.

I'd then look to make check wmi plus compatible with the new interface

Thanks
