Description
We tried another experiment where we wanted to measure the persistence speed for magma on low end VMs compare to high end physical machines. Here are the results:
RAM: 32GB
Dataset: completely in-memory
| Nodes | Shards | Storage | Items | Time |
|---|---|---|---|---|
| 4nodes | 56 shards | magma | 20M | 3 min 15s |
| 4nodes | 8 shards | magma | 20M | 3 min 10s |
| 4nodes | default | couchstore | 20M | 1 min 40s |
PillowFight used for loading:
/opt/couchbase/bin/cbc-pillowfight --spec="couchbase://127.0.0.1:11210/default" --username=Administrator --password=password --batch-size=1000 --num-threads=10 --set-pct=100 --min-size=256 --max-size=256 --random-body --num-items=20000000 --durability=none --populate-only
