A performance issue

[zkk960317]

There may be performance issues in FerriteGmsh, as importing such a small-scale grid actually took 2 minutes.

using Ferrite,  FerriteGmsh
@time grid = togrid("periodic-rve.msh")

Output:

Info    : Reading 'periodic-rve.msh'...
Info    : 38 entities
Info    : 6097 nodes
Info    : 12192 elements
Info    : Done reading 'periodic-rve.msh'

Grid{2, Triangle, Float64} with 11904 Triangle cells and 6097 nodes

Are you on master or latest release?

Are you on master or latest release?

cpu: Ryzen 2700
windows 10 + julia 1.10 + Ferrite 1.0 + FerriteGmsh 1.2.1

Can you upload the grid file?

@fredrikekre periodic-rve.zip
This is from the example "heat equation" in the document of FerriteInterfaceElements.jl.

I think you should try master there are performance improvements on the branch

[fredrikekre]

For me reading that file is around 1 second on both the latest release and the master branch.

I found that most of the time is spent on Gmsh initialization in Line 184 of FerriteGmsh.jl, but I don't know why.

using FerriteGmsh, Gmsh
@timev should_finalize = Gmsh.initialize()

Output:

When I updated Julia to 1.10.7 with Gmsh 0.3.1, the problem still exists.

I sometimes had issues with gmsh on windows, and it worked better with wsl.
Also, just a hunch, did you check the system monitor - did some virus software run heavy (that has given me issues before)
