Disk size has an effect on disk performance. The current standard disk size is 128GB. The following table shows current disk size and speed, as well as the target size and speed for a proposed improvement:
Disk Size (GB) | IOPS Limit | Throughput (MB/s) |
|---|---|---|
128 | 500 | 100 |
1024 | 5000 | 200 |

Case study: DS Disk Size
The data store machine on sandbox had its disk resized from 128GB to 1024GB. OIM layer performance was tested before and after this change and the results are shown in the following graph:

We can see that, if nothing else, consistency has improved greatly. Average response times have dropped from over a second to around 500ms.
Publishing data
Best practices for publishing and symbolizing data must be followed regardless of our hardware.
Create map caches where possible
Data that can’t be cached should be stored and displayed in the fewest and simplest features possible
Follow ESRI’s Performance tips for uncached maps
Re-project all data to WGS84 Web Mercator
Avoid all re-projection on the fly
Debate?
Test performance on all layers?
Web hooks, test new layers?
