I have setup two PA850 in a active passive pair. I am simulating failover manually, when I disconnect the cable, I see around 8 packet drops. Is there any specific settings to reduce the delay. 4 packet drops are acceptable. I have bundled interfaces on the firewall.
Try first with the aggresive failover profile and if needed play with the advanced settings (Monitor Fail Hold Up Time (ms)):
Also if you want better failover because or routing path monitoring see BFD:
you can optimize your failure detection by setting more aggressive timers in device > high availability > general > election settings and setting the HA Timer Settings to 'aggressive'
If you did not do so, configure your aggregate interfaces for LACP and also enable LACP in HA passive state (you'll need to change the passive link state to 'auto' in device > high availability)
