Hi,

Web Hosting is what comes to mind for me. Applications like prestashop,
wordpress,
some custom apps ... I know that I try to use DRBD as much as I can for that
since
GlusterFS makes the sites just way too slow to use, I tried both fuse and NFS
(not
ganesha since I'm on debian everytime though, don't know if that
matters).
Using things like OPCache and moving the application's cache outside of the
volume
are helping a lot but that brings a whole loads of other problems you can't
always
deal with, so most of the time I just don't use gluster for that.

Last time I really had to use gluster to host a web app I ended up installing a
VM
with a disk stored on glusterfs and configuring a simple NFS server, that was
way
faster than mounting a gluster volume directly on the web servers. At least that
proves VM hosting works pretty well now though !

Now I can't try tiering, unfortunatly I don't have the option of having
hardware for
that, but maybe that would indeed solve it if it makes looking up lots of tiny
files
quicker.

Exactly the same here.
Small files workload should be improved a lot

I guess website hosting could be small-file workload related? Tiering may
not help here until we reduce network round trips. I was wondering if
anyone has any write intensive workload that gluster couldn't keep up with
and they had to move to SSDs to make sure gluster works fine with it.

If doing a VM on top of gluster is the kind of solution you are resorting
to. Do you think using gluster-block would be a good idea here? It is still
in development state. We are working on how to get snapshot
functionalities. But if you guys want to test and give us feedback, that
would be very helpful and we can move very quickly to get it in GA state.
