Hello, I know cache occur on client side. My bricks have 32GB of ram allocated. I can see that Linux use it as cache on brick. Do you think I can expect benefits from it and may improve performance by adding more ? If buff/cache memory help gluster bricks what about tuning these: /proc/sys/vm/vfs_cache_pressure (I have mainly many small files and things are slow). I am using version 3.7.1, upgrading to 3.7.2-3 Thanks for your help Regards, Mathieu CHATEAU http://www.lotp.fr -------------- next part -------------- An HTML attachment was scrubbed...
