General

Hi all.
Have VM 10vCPU 64GiB RAM Debian 11
image
And orthanc 1.12.0 installed via LSB.
We have some PC with Radiant and Weasis for doctors.

We got some issue with DICOM Query/Retrive studies after testing getting studies simultaneously. At same time 4 PC can Q/R and 5th cannot (not search nor retrive).
Where is bottleneck?

My orthanc and postgresql config files:

Best regards and thanks for help!

Hi,

This configuration should help:

  // Number of threads that are used by the embedded DICOM server.
  // This defines the number of concurrent DICOM operations that can
  // be run. Note: This is not limiting the number of concurrent
  // connections. With a single thread, if a C-Find is received during
  // e.g the transcoding of an incoming C-Store, it will have to wait
  // until the end of the C-Store before being processed. (new in
  // Orthanc 1.10.0, before this version, the value was fixed to 4)
  "DicomThreadsCount" : 4,

HTH,

Alain.
