VNL needs much time to finish loading projects

[quantumtoday]

Dear all,

Has any one experienced that VNL took much time to finish loading projects? Few days ago, it was still normal but now it takes me about 8 minutes to finish loading projects on my Windows 10 platform. I am using VNL 2016.2 ( I do not have this problem on Linux).

This is usually caused by having many and sometimes big files in the project directories. Are you using the same directories on Windows and Linux?

Hi,

Yes, I used the same directory on both platforms.

I am uninstalling VNL and then will reinstall to see if it helps.

Report: Not better after reinstalling VNL.

I just talked with our developers about it, and it is a general problem that Windows is slower than Linux at handling files. We are working on optimizations, but they will probably not become available for VNL 2016.

Just to clarify: Are you experiencing that VNL is slow to load a project after you have chosen it in the initial dialog or is the initial dialog which is slow to appear? If it is the former, it will help if you can split your work into smaller projects.

Hi Ulrik G.,
Thank you for your prompt reply.
Yes, it is the first case that you mentioned: the project  still linked to the initial directory I chose.  I have experienced this problem after I had more works  (calculations) in the project and the project becomes larger. Now the project size ( the directory size) is about 350 Mb and VNL performs very slowly at loading projects. Indeed, if I divide this project into smaller projects (each about 50 MB) VNL handles pretty well.

Thus the current VNL version does not handle well big projects, we should split into small ones (although it is not convenient since we have to switch between projects). Hope the future versions are better at this experience.

I am happy to hear that the workaround worked. As you have noticed, this is partially related to how things are done Windows, making the problem much smaller on Linux. We are working on it, and it should be less of a problem on Windows in 2017.  However, those sizes are sound small to be experiencing problems. Could you also tell us how many files you have? It is usually the number of files which are causing problems, rather than the size of them.

The "big" project contains 269 files (but a project with 177 files is also very slow at loading), and each small one has 50 files. Hope the information is useful.

Thank you, I will forward the informaiton to the developers.
