I'm wondering if anyone has any tips to improve file/directory operations in HCI replica 3 (no arbtr) configuration with SSDs and 10Gbe storage network. I am running stock optimize for virt store volume settings currently and am wondering what if any improvements I can make for VM write speed and more specifically anything I can tune to increase performance of small file operations such as copying, untar, npm installs etc. For some context, I'm seeing ~50MB/s write speeds inner VM with: dd if=/dev/zero of=./test bs=512k count=2048 oflag=direct -- I am not sure how this compares to other HCI setups, I feel like it should be higher with SSD backed storage. Same command from gluster mount is over 400MB/s I've read some things about meta data caching, read ahead and other options. There are so many and I'm not sure where to start, I'm also not sure which could potentially have a negative impact on VM stability/reliability. Here are options for one of my volumes: Volume Name: prod_b Type: Replicate Volume ID: c3e7447e-8514-4e4a-9ff5-a648fe6aa537 Status: Started Snapshot Count: 0 Number of Bricks: 1 x 3 = 3 Transport-type: tcp Bricks: Brick1: gluster0.example.com:/gluster_bricks/prod_b/prod_b Brick2: gluster1.example.com:/gluster_bricks/prod_b/prod_b Brick3: gluster2.example.com:/gluster_bricks/prod_b/prod_b Options Reconfigured: server.event-threads: 4 client.event-threads: 4 performance.client-io-threads: on nfs.disable: on transport.address-family: inet performance.quick-read: off performance.read-ahead: off performance.io-cache: off performance.low-prio-threads: 32 network.remote-dio: off cluster.eager-lock: enable cluster.quorum-type: auto cluster.server-quorum-type: server cluster.data-self-heal-algorithm: full cluster.locking-scheme: granular cluster.shd-max-threads: 8 cluster.shd-wait-qlength: 10000 features.shard: on user.cifs: off storage.owner-uid: 36 storage.owner-gid: 36 network.ping-timeout: 30 performance.strict-o-direct: on cluster.granular-entry-heal: enable server.allow-insecure: on cluster.choose-local: off
