I too am seeing ~10% CPU usage per Gluster export when using Ganesha NFS. This occurs straight after the process starts and the export does not need to be mounted to see the problem.
Ubuntu 16.04
gluster 3.8.5-ubuntu1~xenial1
nfs-ganesha 2.4.1-ubuntu1~xenial5
I confirmed (as expected, given this is a userspace NFS server after all) that it is not sys and thus strace is no use.
My (test) Ganesha config is as follows:
EXPORT{ Export_Id = 2; Path = /gv0; Access_type = RW; Squash = No_root_squash; Disable_ACL = TRUE; Pseudo = /gv0; Protocols = "4"; SecType = "sys"; FSAL { name = GLUSTER; hostname = localhost; volume = gv0; } }
