We've noticed a massive increase in our Next.js build time as our project has grown. Initially, it took around 3 minutes, but now it's up to 16 minutes. We upgraded from Next.js v14 to v15, hoping for improvements, but saw no difference. After analyzing the trace file using trace-to-tree, it looks like node-file-trace-plugin is taking up a significant amount of time(not sure why). Interestingly, builds are relatively faster on our local Windows machines (~ around 7 minutes with Microsoft Defender disabled) compared to our Linux server.
