Performance comparisons between NetBox 3.7 and 4.4

[markkuleinio]

Using simple pynetbox calls, without threading, for raw comparison:

NetBox 3.7.3 (on PostgreSQL 13.20 on Amazon RDS):

NetBox API 3.7, pynetbox 7.5.0
nb.dcim.devices.all():
Run 1: 3.24 seconds, for 1856 objects
Run 2: 3.31 seconds, for 1856 objects
Run 3: 3.46 seconds, for 1856 objects
nb.dcim.devices.filter(exclude="config_context"):
Run 1: 4.16 seconds, for 1856 objects
Run 2: 3.68 seconds, for 1856 objects
Run 3: 3.49 seconds, for 1856 objects
nb.ipam.prefixes.all():
Run 1: 23.77 seconds, for 15467 objects
Run 2: 23.54 seconds, for 15467 objects
Run 3: 24.19 seconds, for 15467 objects

NetBox 4.4.4 (on PostgreSQL 17.6 on Amazon RDS):

NetBox API 4.4, pynetbox 7.5.0
nb.dcim.devices.all():
Run 1: 3.93 seconds, for 1856 objects
Run 2: 3.37 seconds, for 1856 objects
Run 3: 3.74 seconds, for 1856 objects
nb.dcim.devices.filter(exclude="config_context"):
Run 1: 3.52 seconds, for 1856 objects
Run 2: 3.59 seconds, for 1856 objects
Run 3: 3.44 seconds, for 1856 objects
nb.ipam.prefixes.all():
Run 1: 52.53 seconds, for 15464 objects
Run 2: 52.43 seconds, for 15464 objects
Run 3: 51.72 seconds, for 15464 objects

Using threading=True in pynetbox brings about 15% improvement on the prefixes.all() calls for both 3.7 and 4.4, no difference in the devices.* calls.

Edit: added psql versions above.

I have the feeling that netbox It's gotten slower. I upgraded from 4.x to the latest version, and scripts have gotten noticeably slower to run.
