WSO2AM version : 1.10.0
I setup API manager after reviewing deployment pattern document.(https://docs.wso2.com/display/CLUSTER44x/API+Manager+Deployment+Patterns)
1 publisher
1 store
1 Gateway manager
3 Gateway worker (Clustering)
2 Load Balancer
2 Key manager (HA)
4 jmeter slaves , 1 jmeter client
and then I did failover test with jmeter. I killed one gateway worker node, during jmeter generating http requests. (gateway worker node 3 -> 2)
I got the result different to that I expected. (little strange) TPS dropped close to zero for 5 seconds, when a gateway worker process shutdown. (when I killed the gateway worker)

I wonder what happen that point? Even though alive gateway workers try to recover something, I didn't think TPS would drop like that.
