Hi Blaine, Just some hunches:
* a big project may slow anything down that wants to scan the overall project. * You might want to give netbeans more memory to work with. e.g -Xmx6g added to the command line or in the settings file netbeans.conf * splitting the project up into smaller pieces smaller projects) and opening only those that you need to edit may also help. In such setup you only build the open projects and re-use the results of other builds. A typical project of this size will have several phases|layers|components that could be neatly packed into separate artefacts (e.g. when using maven). Kind regards, Met vriendelijke groet, Pieter van den Hombergh.
