Local REST API is very slow

BETA BETA API

Team,

I am working on an open source Home Assistant project adding an integration for Bond Bridge, see the PR: https://github.com/home-assistant/core/pull/37477

I am using your local REST API to discover a list of devices and their properties. I noticed that it is extremely slow, about 5 seconds per each REST call - I make one request to get device IDs, and than 1 REST call for each of 3 devices to describe them - this takes ~20 seconds.

Is there some rate limiting or other reason why this is so slow? Any way to avoid the slowness?

Thank you!

Are you noticing the same lag when calling the API commands via command line or REST-based program (such as Postman or similar)?

I wonder if the HA method you’re using to call the API commands is somehow adding a layer of lag (waiting for a response different from what it is receiving or something)?

I don’t have any substantial lag issue unless the Bond Bridge has fallen off the network or otherwise frozen (very rare) - but then I hit timeout and no reply vs getting the reply slowly.

No, I have the same problem with Postman. For example, calling simple /version endpoint takes 5 seconds:

I did realize just now though that it is slow when I use mDNS entry created by Bond in the request - bb16962.local. If I use IP address instead - requests are fast. Not sure what to make of it…

Ah, yes. Good callout.
Cross-platform support for mDNS seems iffy.
I have come to instead rely on IP addresses for the Bridges.
