Hi! I'm a newbie in supporting Azure services for a client. I would like to know if there is an impact in performance and pricing when increasing the Azure appgw timeout of our setup? Currently, we have a premium subscription and our gateway is configured with WAF V2 tier autoscale 0-10, and timeout is at default 20sec in prod (60s in staging). In the website, https://azure.microsoft.com/en-us/pricing/calculator/ , I can see that capacity unit (compute unit, connections, and throughput) are variables in computing monthly cost. Will this pricing computation be impacted by the change in timeout? How about the app gateway performance, and connection to APIM service?
The current average capacity of APIM is at 12% and maxing at 25%. While request is currently at around 200 per minute which is far from our current subscription 4000 per seconds.
