When using the verify tool the images take up to 3 minutes to be created.

Do you mean image loading, or approval?

Image loading

@sebastiangaertner I'm not seeing any issues with image loading in production. I'm using a South Africa VPN to get as close as possible, but images are loading quickly as Admin and as Freetown Manager.

Can you upload a video clip of the loading and a screenshot of the Network tab in developer tools?

Its irratic really. Maybe there was some rebuild of the droplets happening. Its still slow for me see video here https://youtu.be/JaoOa_T-sac
Mind that i have not heard any complains about this so it could well be a my internet. The question can we monitor how long images take to be created? At some point this could be part of SAAS packages. Also maybe a good idea to calculate how much cimputing goes into verifying one tree and storing its data over time. We will get asked this question when it comes to scalability and the earlier we start knowing averything about it the better. What do you think?

Apologies @sebastiangaertner, I didn't realise you meant image resizing when you said creation.
Tests on the prod image resizing API show a speed of about 200-400ms to resize and return the image using a fast connection.
Slow loading is most likely caused by a slow connection, as you suggest.

If you open the Network tab in the developer console, you'll be able to see how long each image takes to load and the breakdown of the timing. I'd be interested to know if your browser is trying to load all 24 images for the page at once, or just the images in the viewport.

I'm sure it would be quite straightforward to extract some time metrics from the microservice logs or possibly Ambassador.
As for the compute (I take it you ultimately mean energy consumption), that's a question for the cloud team (but an important one).

Thanks Nick. I will discuss with the cloud team.
