How to improve the performance of HoloLens when live streaming video from PC to HoloLens?

I think the issue was by ths following , Your procedure inside the load_image() should theoretically work.
BUT it's a really bad practice to start a coroutine every update() frame loop. Better start one coroutine and use a never ending loop with a WaitForSecond() break. This way you can try out what is the maximum repeat rate the hololens can handle.
void Start () {
     StartCoroutine(StartImageLoading());
 }

 IEnumerator StartImageLoading () {
     while(true){ // This creates a never-ending loop
         yield return new WaitForSeconds(1);
         LoadImage();
         // If you want to stop the loop, use: break;
     }
 }

wish help you to fix your issue Solved this by adding a command in the object controller that set its position based off of the inverse transform point of the shared world anchor when someone gained authority over the object. Looks something like this:
private void Update()
{
    if (receivedAuthority)
    {
        Vector3 objDir = transform.forward;
        Vector3 objPos = transform.position + objDir * .01f;

        localPosition = sharedAnchorTrans.InverseTransformPoint(objPos);

            CmdTransform(localPosition);           
    }

   else if(!receivedAuthority)
    {

         transform.localPosition = localPosition;

    }
}

[Command]
public void CmdTransform(Vector3 position)
{
    if (!isLocalPlayer)
    {
      localPosition = position;
    }
}

Microsoft HoloLens: Mixed Reality 250 - No session available for one HoloLens to join with another HoloLens hosting it

this one helps. I followed Dtb49's comment, where I used my own cell phone with mobile hotspot enabled; I finally see the session I want to join!
Now I can share holograms between the headsets through networking by just air tapping on the option showing the name of the device.

How to transimit video streaming from HoloLens (C#) to PC (python) by socket communication?

may help you . To send video steaming in real-time between HoloLens and PC client, WebRTC should can meets your needs. Please check out this MixedReality-WebRTC project, it can help you to integrate peer-to-peer real-time audio and video communication into your application. It also implements local video capture you need and encapsulation it as a Unity3D component for rapid prototyping and integration.
You can read its official documentation via this link: MixedReality-WebRTC 1.0.0 documentation.

I wish did fix the issue. Here's a great blog post by one of my fellow Microsoft MVPs... :)

How do you detect whether your Mixed Reality app is running on HoloLens 1, HoloLens 2 or an immersive headset?

help you fix your problem If you are using MRTK (I noticed you might based on your tag), then the best way to do this is by using platform capabilities utility, since that will work as new devices come out, and across platforms. For example, instead of checking "am on on HoloLens 2" you can check "does my device support articulated hands?". That will then work on other platforms that support articulated hands. For an example, chekc out MixedRealityToolkit.Examples/Demos/Utilities/Scenes/MixedRealityCapabilityDemo.unity in MRTK examples.
If you need a temporary solution for now to differentiate WMR from HL1 from HL2, you can use the following code. Note it's windows-only:
using Windows.Security.ExchangeActiveSyncProvisioning;

EasClientDeviceInformation CurrentInfo = new EasClientDeviceInformation();
string sku = CurrentInfo.SystemSku;
