preload-rs

preload-rs is a daemon process that prefetches binary files and shared libraries from the hard disc to the main memory of the computer system to achieve faster application startup time. preload-rs is adaptive: it monitors the application that the user runs, and by analyzing this data, predicts what applications he might run in the near future, and fetches those binaries and their dependencies into memory.

It builds a Markov-based probabilistic model capturing the correlation between every two applications on the system. The model is then used to infer the probability that each application may be started in the near future. These probabilities are used to choose files to prefetch into the main memory. Special care is taken to not degrade system performance and only prefetch when enough resources are available.

Design

preload-rs has been divided into the following crates, with each crate serving a specific purpose. They are:

• cli: Responsible for launching preload-rs process. It is a binary crate.
• config: Manages configuration for preload-rs. It is a library.
• kernel: Manages the core functionality of preload-rs. It is a library.

All crates reside under crates/ directory.
