+BENCHMARKS
+
+The speed of go-fuse is close to libfuse's speed (measurements on my
+lenovo T60 laptop):
+
+* 'find' in tree with 14k files. fs access: 0.06s, go-fuse: 3.5s, bbfs: 3.9
+* 'ls -lR' in same tree:  fs access: 0.5s, go-fuse: 9.5s, bbfs: 8.8s
+* copying a 100 mb file: fs access: 200mb/s, go-fuse: 182mb/s, bbfs: 190mb/s
+
+bbfs is a loopback filesystem written in C, see
+http://www.cs.nmsu.edu/~pfeiffer/fuse-tutorial.tgz
