I'm working with the API, but I noticed requests are quite slow. Each request seems to take between 8-11 seconds. I timed different requests and the time doesn't seem to differ much between search and getting a specific question for example.

Is it a performance problem on the backend or is it something on my side?

Edit

It seems there was some networking issues which I now fixed. However, search requests are still very slow and taking about 9 seconds. For instance:
