I am starting to work with and benchmark our ceph cluster. While
throughput is so far looking good, metadata performance so far looks to
be suffering. Is there anything that can be done to speed up the
response time of looking through a lot of small files and folders?
Right now, I am running four metadata servers and the filesystem is
mounted via fuse.
We use module to manage environmental variables for the applications on
our cluster. When I type "module avail" it takes about 30 minutes to
get a response the first time with a pair of my monitors running at 100%
during this time. Later ones are near instantaneous.
