Change in softirq pattern with 23.05

Hi. With the recent upgrade to 23.05 i started to see changes in softirq usage patterns.
With 22.03 the softirq were concentrated in cpu0, and with the 23.05 it seems more balanced between the four cores.
The gap in the stats is the time between i turned of with 22.03, and upgraded all packages and restablished the collectd service.
Hardware: Linksys MR8300
Target: ipq40xx/generic

Is this expected behavior?
Thanks.

(cores #1 #2 and # have very similar graphs, so i post only #1)
