fps reduces when image analysis usecase is applied

I'm testing on

TECNO POP 2F (b1f)
CPU Core-Count = 4
RAM = 1.00G
Internal Storage = 16GB
Screen Resolution = 960 X 480

I'm using the CameraXBasic Example

The camera preview gets laggy only when the ImageAnalysis use case is applied.

I observed that without the imageAnalysis usecase the frame per seconds is approximately 10 on this device even tho the device will support up to 30fps (Range(lower=30, upper=30)

*Below are the supported fps Range*
Lower => 20, Upper => 20
Lower => 24, Upper => 24
Lower => 5, Upper => 30
Lower => 30, Upper => 30

When ImageAnalsis usecase is applied the fps drops to approximately 3fps

I/BufferQueueProducer: [ImageReader-864x480f23m4-18676-0](this:0x98965000,id:0,api:4,p:18676,c:18676) queueBuffer: fps=2.50 dur=1199.65 max=416.04 min=384.55

And i think this makes the CameraPreview Lag.

Are there any optimization techniques that can be applied to avoid making the preview lag?

I've attempted setting the fps myself but i don't think that has any effect

e.g

```kotlin
val builder = ImageAnalysis.Builder()
// We request aspect ratio but no resolution
.setTargetAspectRatio(screenAspectRatio)
// Set initial target rotation, we will have to call this again if rotation changes
// during the lifecycle of this use case
.setTargetRotation(rotation)
// The analyzer can then be assigned to the instance

val camera2Interop = Camera2Interop.Extender(builder)
// camera2Interop.setCaptureRequestOption(CaptureRequest.CONTROL_AE_MODE, CaptureRequest.CONTROL_AE_MODE_OFF)
camera2Interop.setCaptureRequestOption(CaptureRequest.CONTROL_AE_TARGET_FPS_RANGE, Range(30, 30))

```

Inizia con il CameraXBasic Example e il relativo caso d’uso ImageAnalysis, riproducendo l’anteprima sul TECNO POP 2F indicato con e senza analisi. Esamina la configurazione di ImageAnalysis.Builder e confronta i frame rate riportati; il lavoro è completato quando viene identificata una causa confermata e viene documentata o testata una modifica che impedisca all’anteprima di scendere a circa 3 fps.
