Description
The CernVM-Filesystem (CVMFS) is a global, read-only, on-demand filesystem optimized for software distribution. Its on-demand nature is well adapted and extremely efficient for distributed batch computing, but can mean noticeable latency in interactive use, especially when working with applications such as python that load a large number of small file on startup.
In this contribution we present CVMFS file bundles, a new feature that allows repository owners to increase startup performance by defining lists of files that are known to be loaded together and can therefore be requested asynchronously by the client, and benchmark startup performance of common applications.
