While a release with this patch merged/tested is another 50days away, we surely
would like to reduce the CPU load you see too. Whenever you get time, if you
can capture CPU info with below tool "perf record -ag --call-graph=dwarf -o
perf.data -p <pid of glusterfs process>", and then see "perf report" to see
what actually caused the CPU usage, it will help us to resolve that too.

Also note, lru-limit=10000 while many files are accessed may not be a good
value. I recommend something like 64k at least. But well, it depends on your
memory needs too. So, if you can give 512MB - 1GB RAM for glusterfs, its better
at least for performance.
