Thanks! Ya I'd like to add macOS support at some point to vmprobe, but I'm using a bunch of linux-specific stuff at the moment: mostly pagemap/kpageflags, although also some mmap/madvise flags that are linux extensions. Still, the basic use cases don't need this. Regarding your web-app, it's possible that you are touching a bunch of files that you don't need to. Rarely-accessed static files, the .git directory, and so on. vmprobe snapshots might help here, or you could figure out which files are used for start-up and just touch those. There's also the -I switch. You might try something like: vmtouch -t -I '*.html' -I '*.js' -I '*.css' /var/htdocs/ Also, sometimes it is possible to page in the necessary files before your web-app is started, or concurrently while it's starting (maybe at boot-time, container start, etc). Also, sometimes assets are paged in before the first request is received. I know of quite a few people and companies that use vmtouch in their daily workflows. vmprobe is still largely experimental at this point though.
