Google vision API: Slow response times

Thanks for stopping by to let us know something could be better!

PLEASE READ: If you have a support contract with Google, please create an issue in the support console instead of filing on GitHub. This will ensure a timely response.

Please run down the following list and make sure you've tried the usual "quick fixes":

• Search the issues already opened: /~https://github.com/googleapis/google-cloud-ruby/issues
• Search StackOverflow: http://stackoverflow.com/questions/tagged/google-cloud-platform+ruby

If you are still having issues, please be sure to include as much information as possible:

Environment details

• OS: MacOS
• Ruby version: 3.3.6
• Gem name and version: google-cloud-vision (1.5.1)

Steps to reproduce

1. Call the API and pass an image
2. The API call works and I get the response, but the response time is huge (approx 77 seconds). If I use the Rest API, I get very quick response for the same image.

Code example

require "google/cloud/vision"
    require "time"
    require "base64"

    # Initialize the Vision API client
    vision = Google::Cloud::Vision.image_annotator

    image_path = Rails.root.join("app", "assets", "images", "cookie.png")
    image = File.open(image_path, "rb")


    # Cloudinary URL of the image
    # image_url = "https://res.cloudinary.com/dqstmox0s/image/upload/v1736173018/cookie_zqljqk.png"

    # Start measuring time
    start_time = Time.now

    # Perform text detection (OCR) on the image from the Cloudinary URL
    begin
      puts "Calling Vision API..."
      # Sending image URL for OCR
      response = vision.text_detection image: image

      # End measuring time
      end_time = Time.now
      duration = end_time - start_time

      # Print the time it took
      puts "OCR request took #{duration} seconds."

      # The response contains multiple results in 'text_annotations'
      if response.responses.any?
        # Get the text annotations from the first response
        annotations = response.responses.first.text_annotations

        # Print the detected text
        raw_text = annotations.first.description
        split_text = raw_text.split("\n")
        text_to_match = split_text[0]
        puts "Detected text:"
        p text_to_match
      else
        puts "No text annotations found."
      end
    rescue StandardError => e
      puts "An error occurred: #{e.message}"
    end

Full backtrace

Calling Vision API...
OCR request took 76.694712 seconds.
Detected text:
"Image text"

Could there be some kind of configuration issue? I was thinking which endpoint it's calling (Europe or US), but this seems to work properly with the generic endpoint when using the REST API.

Thanks for your help!
