Thank you very much Erekle for your links, they are all relevant to me and very
interesting as as you mention I will be mostly serving a lot of rather smaller
files from my containers.
I will first consider upgrading my gluserfs from 3.8 to 3.10 to take advantage
of the small file performance improvements which is afaik newly available in
3.10.
Best regards,
M.
