One pool with multiple VIPs using it-how many health checks will occur to the members?

If there is one pool but multiple VIPs using that pool, does the number of VIPs affect how many health checks hit the member nodes-meaning the more VIPs the more health checks?

 

The member nodes are getting 20+ healthchecks a second sometimes. The interval is every 5 seconds for the members.

    Health check is defined on a per-pool or per-pool member basis. Number of VIPs/Virtual-Servers using a single pool shouldn't cause the number of health-checks to increase in number. Assuming all the pool members serve similar function (usually the case), it is recommended to have a single health check at the pool level and make sure the pool member's inherit this health check.
