Yes, Wing does look in all directories off the Python path for things that might be packages, which could take a long time depending on what you have. Perhaps we can improve this either by making the backgrounding less aggressively compute-intensive (by doing it more slowly) or by limiting the scope of its search. We already plan to add indication of when source analysis is busy, which will hopefully make it clearer when this compute intensive task is going on. One question: Does it still do this now or is startup faster? I'm wondering whether reading and validating the analysis cache is also an issue for you, or just the initial scan. In any case, thanks very much for finding the cause of this! - Stephan
