[Gluster-users] Description of performance.cache-size

[Shreyansh Shah]

Hi Strahil,
Thanks for taking out time to help me.

This is not a hyperconverged setup. We have 7 nodes with 2 bricks on each
node. Total 14 node distributed setup.
The host on which i saw the increased RAM is a client with glusterfs client
version 5.10.
