I solved 1-d poisson equation using julia 1.6.2 with BoundaryValueDiffEq package, it is taking very long time to solve. Same problem is taking less than a minute in python’s scipy.integrate.solve\_bvp. Could anyone help me in figuring out the problem in the code. I have appended the file link here [MOSPoisson.ipynb - Google Drive](https://drive.google.com/file/d/1awoW3gwnimsLjy1xjAUZ9lgUEQFmx4mz/view?usp=sharing)

Yes, it’s non-adaptive right now so it’s not great.

Thanks Chris, so is there any other Julia package for getting this faster

[https://github.com/luchr/ODEInterface.jl](https://github.com/luchr/ODEInterface.jl) has some wrappers of BVP solvers that might do a little bit better until we improve in this domain.

Thanks, I will solve it this way then
