OHIF very slow to load DICOM

General
1

Hi
I installed 2 orthanc servers (V1.12;2 on windows with dicom storage in a NAS connected to the same switch as the server) in 2 different hospitals (first with +/- 3000 series, the second +/- 13000), with some Clearcanvas for advanced and OE2/Http for basics users
Orthanc works well, but I have problem with the http viewers

Tried Osimis (but I read somewhere it is deprecated), Stone and OHIF
Osimis has a strange behavior on one server, but I don’t think I’ll go with this one (deprecation)

Stone seems to works well (10sec to display), but OHIF is very slow (more than one min, and even much more) to load the Dicom images, and sometimes (especially if the serie has multiple instances) never ends in slow connexions
Any idea?
Should I get rid of OHIF? but why? is it a “bad” viewer ?

Thanks

No OHIF is not a bad viewer.

First, you should open your browser dev tools and check which HTTP call is taking a lot of time and also check the Orthanc logs in verbose mode to check timings …
