Performance refernce

Hello,
Petasan is very new to me and I am looking for reference values. I would be happy if experienced Petasan users could give me an estimate of the expected performance.
Setup:
3 x cluster nodes with the following features each:
2 x Intel E5-2650 (20M 6.00 Cache, 2.00 GHz, 8.00 GT/s Intel
128 GB Ram
4 x 8TB Seagate Enterprise Capacity 3.5 ", 4Kn HDD as OSD
1 x 500GB M2 SSD as Journal
2 Replicas

With PetaSan 1.5:

Cluster Benchmark, 4K IOPS rados benchmark, 1 thread, 1min, 1 client = 506 Write / 2053 read
Cluster Benchmark, 4K IOPS rados benchmark, 8 thread, 1min, 1 client = 2338Write / 15633 read

Thanks for your info / help!

Hi,

Performance varies a lot with hardware and network.  The values look good, given you are using spinning disks which have iops limits. It will be good to benchmark your throughput MB/s as well. If iops is more important to you than throughput then consider using an all ssd/nvme solution and not hdds.

Another thing is most probably your 4 x hdds per node is a low number and  you can double or triple  performance by adding more 4 x hdds + ssd journal. The resource load report that is generated will help you know which resources are the most busy and are therefore your main bottlenecks.
