Subject: [PATCH] gnu: system: vm: Use loose cache for 9p file system.
Date: Sat, 16 Dec 2017 19:20:18 +0000

This improves the performance of the shared store for operations involving
lots of files, e.g. searching through the store.

* gnu/system/vm.scm (mapping->file-system): Add cache=loose to options.
