We started using NPA for our Radiologists; they connect from home [1Gb ISP connection] via NPA [two publishers] to our on prem PACS system.
PACS studies/Images are pretty big, some studies are 2 GB+ in size. We are on 22.214.171.12494 for the publisher and per the release notes, this version supports peak throughput of 500 Mbps. But unfortunately we are not seeing that.
In testing the Peak, we notice is only ~120Mbps. We have set up a speedtest docker container just for this purpose and published it through NPA.
Wondering if anyone has thoughts on how to increase the throughput so the images load faster as some of our rads reported slowness in loading the studies.

Hi figured I would give you more data.
- Home (1gbps download/150mb upload)
- to/from one of the two NPA Publishers in Azure.
- NPA v126.96.36.199
- Client v188.8.131.520
- NPA Gateway 184.108.40.206 (CA-YYZ1 Toronto).
Just did home to internal network SMB:
- Pulled a 1.4GB file between 120-180mbps
- Uploaded a 4GB file between between 100-150mbps (upload being the limited factor)
