This will lower the petitions to MDS and CPU usage, right?

My last question is if someone can recomend me a good client configuration
like cache size, and maybe something to lower the metadata servers load.

I forgot to say that after upgrade the machine RAM to 4Gb, the OSD daemons
has started to use only a 5% (about 200MB). Is like magic, and now I've
