You can google the specs for the raspberry pi 3, but it’s about what you described. And yes, it’s either a USB or MicroSD that it’s reading from, but that problem was already eliminated by the core plugin file fix above and it still takes 56 seconds for TiddlyWiki Node to load the core and run the version command, so there’s more to be investigated. It could still be paging to disk, as you mentioned, but the TiddlyWiki boot sequence will only read about 7 files in this case.
