On the topics of edit time performance.... Over the last month I've been developing a test system that is now around 650 custom Vis in memory at one time. I started to notice a quickly increasing load on windows from LabVIEW towards the end of the project that disappeared after removing the SVN toolkit. I'm sure it depends on the processing power of your machine but I find that the 500+ VI projects start to see some major impact from the Viewpoint add on. It's a fantastic tool, but that's the trade off. Cheers, Tim

That's a very old recommendation back in the days when NI added source code control integration to LabVIEW (version 6 or 7 or something like that). They used the Microsoft source control API for that which was only really supported for the now defunct Microsoft Source Safe offering. Some companies developed additional plugins for that API that interfaced to other source control solutions but the Source Safe API used the old checkin/checkout methodology like what CVS had been using and didn't support any of the other methods like what SVN, Hg and Git nowadays support. As such the Source Safe API was severally limited and never really could catch on, probably also helped by the fact that Source Safe was a notoriously bad source control system, that could actually corrupt your source code randomly if you were unlucky. NI later improved the source control interface in such a way that you could install LabVIEW based source control provider plugins, so if you want to use SVN and have it integrated in LabVIEW directly you should probably install the Viewpoint SVN plugin instead. The only problem with LabVIEW based project plugins is however that they can affect the performance of LabVIEW IDE operations. There have been reports that installing any of the LabVIEW SVN plugins start to severely impact edit time performance if a LabVIEW project file reaches a certain number of VIs. But PushOK SVN is certainly the worse solution for use with LabVIEW. That all said we use SVN for our development, but we usually don't install any source code control plugin in LabVIEW. Most simply use the Tortoise SVN Windows shell integration. You have to be careful when moving, renaming, or deleting files as you have to make sure to first do those changes in Tortoise SVN and then change the project to reflect the new situation but it works pretty well if you keep yourself disciplined.

Haven't forgotten this but there needs to be some more work done as I also updated the whole source code of the shared library in the past and I need to do some more tests. But for now I'm taking off for some well deserved vacation.
