Problem with PfSense 2.4.2-RELEASE-p1 HA CARP

[alkaid]

Hello all,

I have a cluster of two nodes in high availability.
The HA is functioning properly.
A customer reported to me that the response time was slow.
After looking for a long time, I noticed that when I stop on the fwa the CARP protocol, the response time of my pages is divided by 5-6 !!!
Do you have an idea of the problem ?
A big thank to all.
