I am not sure what you mean.  
If data is equispaced then the interpolation is, as the name suggests, becomes a convolution operation.  
Since you did not use any other package, I was wondering how fast your convolution implementation.  
Have you compared your implementation of 1D convolution to other implementation in the eco system?

For instance:

1. [ImageFiltering.jl](https://github.com/JuliaImages/ImageFiltering.jl).
2. [DSP.jl](https://github.com/JuliaDSP/DSP.jl).
3. [Optimizing Direct 1D Convolution Code](https://discourse.julialang.org/t/97658).
