What is the impact of activating Connection Mirroring?

I understand the impact varies significantly depending upon specific configurations but when we activated connection mirroring for non-HTTP connections there was no observable impact on single-bladed Viprion. Peaking at about 1Gbps mirrored. From my readings this is unusual and impact should be expected. All that traffic glides over your HA link so that could be problematic if it isn't dedicated/direct-link.

 

 

Although not performance related, the iRule-fires-on-Standby issue still exists in 11.2.1 HF3. I see with 11.4 there is an iRule that allows awareness of Active/Standby so the rules can be told not to run on Standby.
