I haven't tested it myself yet, but some devs suggested that slow session startup (as opposed to slow booting to login screen) may be caused by homedirs stored on NFS. Might be worth adding a test account that has a homedir "native" to the server, and if that brings a significant speed increase, trying out other networked filesystems like glusterfs. Might be possible, NFS migh probably add a few latency but I wouldn't recommend using GlusterFS instead, it is far slower due to the voulme beeing mounted through Fuse. I already did many testing on GlusterFS for our internal usage and it is by far slower than NFS. CephFS (file sharing "nfs like" filesystem provided by Ceph on top of it's storage capabilities, as opposed to the "usual" block mode it provides) could be worth trying but I didn't had the opportunity to do some testing by now. Anyway, I think it should be at most comparable to NFS, not really faster.
See, you "think", but you haven't verified it in comparison to a local homedir. As I said, I haven't either, but it was a hint from some of the devs to look out for that. So maybe we just have to live with a slower session startup if networked homedirs are part of the equation; testers to confirm or dismiss this theory are welcome. ;-)
