the find usage function is very slow. 执行“查找使用”右键菜单功能太慢了，执行一次要50秒以上

I confirm the problem of slow "Find Usages (Module) Ctrl+Alt+U" on go1.23.1 too. It looks like the "Find Usages..." slowed down a lot when LiteIDE was migrated from ver x36.3 to ver 37.1. In ver x36.3 and earlier, only gotools.exe was used for search and it worked fast. In ver 37.1 and later, the search is additionally used several go.exe-processes and it all works slowly.


LiteIDE is a great app! I would not like to leave it...
