vmtouch can't replace ramdisk for write-only or mixed workloads.

What is vmtouch?

vmtouch is a tool for learning about and controlling the file system cache of unix and unix-like systems. It is BSD licensed so you can basically do whatever you want with it.

What is it good for?

  • Discovering which files your OS is caching
  • Telling the OS to cache or evict certain files or regions of files
  • Locking files into memory so the OS won't evict them
  • Preserving virtual memory profile when failing over servers
  • Keeping a "hot-standby" file-server
  • Plotting filesystem cache usage over time
  • Maintaining "soft quotas" of cache usage
  • Speeding up batch/cron jobs
