This could be presented as either a one-off dump file or a continuous ring buffer. A large number of individual command-line options control what data is being captured. In addition, JFR can capture more than a hundred different possible metrics.

Bigger buffers can lead to wasting memory, on the other hand, smaller buffers can throttle the reader's or writer's application because there won't be any space for transferring bytes to/from the

VLIB (Vector Processing Library)¶ The files associated with vlib are located in the ./src/{vlib, vlibapi, vlibmemory} folders. These libraries provide vector processing support including graph-node scheduling, reliable multicast support, ultra-lightweight cooperative multi-tasking threads, a CLI, plug in .DLL support, physical memory and Linux epoll support.
