Krutika Dhananjay 2018-12-14 12:34:42 UTC Doc Text Feature:
The feature adds support for multi-threaded fuse reader threads, which means now parallel requests on a fuse mount can be handled by multiple threads. Earlier all requests used to be handled by a single reader thread.

The default value is still 1. The user can specify number of threads to use as a mount option as - ... -o reader-thread-count=N ... - where N is the number of threads.

Reason:
Under high load, the lone fuse thread can hit near-100% CPU utilization, and become a performance bottleneck. This can be worked around by increasing the number of fuse threads.

Result:
Having multiple reader threads can give better I/O performance.
