Description

Calling API https://rudder.example.com/rudder/api/latest/nodes is super slow : 15s with 350 nodes
Same call with https://rudder.example.com/rudder/api/4/nodes is only 0,2s

We probably broke something in the latest version

Targetting to 3.0, but I'm not sure of the actual version of latest that is slower

I can't reproduce that one. I have a test machine with ~2000 nodes, and both are extremelly fast.

Have you more information about the environment where the problem happens?

On an other (more realistic) rudder instance, we have a little difference.

- full lastest (api v6):
time curl -k -H "X-API-Token: ...." -X GET 'https://otherrudder/api/latest/nodes'
0,02s user 0,00s system 1% cpu 0,970 total

- only what was reported in previous api:
time curl -k -H "X-API-Token: ...." -X GET 'https://otherrudder/api/latest/nodes'?include=minimal
0,02s user 0,01s system 2% cpu 0,863 total

- api v5:
time curl -k -H "X-API-Token: ...." -X GET 'https://otherrudder/api/5/nodes'?include=minimal
0,01s user 0,01s system 9% cpu 0,255 total

This is of course higly non-scientific, because data with one try... But we can clearly see a 4x in total time, between API v5 and api v6 (between the two api v6 call, we can guess it's just because there is so much more data returned).
