There are three essential resources that every computer needs: processor (CPU), memory (RAM), and storage. Replit users' computers have access to a virtual CPU, RAM allocation, and a virtualized filesystem. The new resource utilization component helps users understand why their repl is running slowly or misbehaving by providing information on CPU and RAM usage. Modern computers run multiple programs at once, with the operating system allocating CPU time to user applications. CPU utilization measures the difference in time spent executing instructions over a given interval divided by wall time, taking into account available CPU cores. Replit users have access to 0.5 vCPUs for free plans, 2 vCPUs for Hacker repls, and 4 vCPUs for Boosted repls. RAM is used to store program values at runtime, with more programs requiring more RAM. Users have limited control over memory usage, but can test it by running a program that allocates large amounts of memory. The new resource monitoring component shows how much storage space is being used in the repl's filesystem, which is currently limited to 1 GB. Understanding these resources and their utilization can help users optimize their Replit experience.
