However, my performance bottleneck with Xpand/Xtend/Check is not the execution of the language but the refresh resources of the entire workspace that the workflow does automatically. I have a huge workspace with > 30,000 files and it takes up to 10 minutes to refresh the entire workspace (if the windows file cache is empty). And even if everything is in the cache it takes 15 seconds. I have 5 related languages. If I change the 'base language' I have to run 5 workflows which takes between 3 min and 12 min (including stating the workflow, refresh and building the workspace). Only about 40 - 50 seconds are really xtext/xpand/check execution time. Michael Michael This is really cool!
