Also, as a suggestion coming from another conversation between Eric and Ram, you might want to check performance with metrics disabled - the current ESMetrics implementation may not be coping under high load. apiman-gateway.metrics=io.apiman.gateway.engine.impl.InMemoryMetrics apiman-manager-ui.metrics.enable=false We'll look at optimising it; shouldn't be difficult.

Hi Marc, - Measured the time it takes to do your custom auth calls? Just to quantify what the effect of the policy is. For example you could print out timestamps, and/or compare to a deployment with no custom policies set. [Manav] – There calls are very fast, we did test it, as there is a Redis backend. I tested it. - Tweaked JVM memory settings and/or GC? [Manav] – Well said, we tried it to find the best setting. - Increased the thread-pool sizes? [Manav] – Well said, we tried it to find the best setting. One straight question, can Elastic Search be a bottleneck? Will there be difference if we use RDS instead of Elastic Search? How heavy metrics calls to ES?

We don't want to upload files directly to S3 as there are few custom authentication & auth(via Redis In-Memory DB/Cache) checks we perform via our custom plugins in APIMAN. While, our APIs run OK without APIMAN, we see response time degrading considerably with APIMAN. What could be some of the best practices we should follow for performance tuning? We tried WildFly & Tomcat, though latter comparatively performed better, overall response time didn’t improve much.
