Problem with a time #953

Open bogdanov-i opened 2 years ago

bogdanov-i commented 2 years ago

Hello. I have a problem. I use CompreFace Verification to compare 2 user photos. The project is deployed on the CPU. I don't use GPU. The server capacity is as follows: -4 Core; -16 Gb;

How much should the request be processed compared to? My comparison takes about 6-10 seconds. What is the normal value?

pospielov commented 2 years ago

Photo processing speed depends on many factors: image size, number of faces on it, CPU architecture, and others. But I would expect it to be from 100ms to 1 second.

It's definitely atypical. Did you try it on another server or a personal PC? Is CompreFace utilizes all resources (CPU and RAM)?

Hello. Image size: 480p (480x640); Image quality and format: Jpeg (100); Image: 1 face, 15px each side of the face, 30px each top and bottom of the face; Server: 4 cores, 16 Gb. We use Selectel. There are no restrictions.

We took Compre Face, wrapped it with RestTemplate to make the interaction logic we need, namely: we need to form a response template. This led, in our opinion, to an increase in delay by 1-2 seconds. But, then, the spread should be in the region of 4-8 seconds, but this is not typical either.

Which server should we use? What requirements should he have?

The server should be enough. You can try it on your personal PC using UI. It should work much faster than 4-8 seconds. Just one thing to notice - the first two requests are always slow because of server initialization.
