I was trying to migrate node.js application into docker containers.
When I did some API load test onto our applications which ran in docker containers, I found some API response time were beyond 10 seconds in New Relic.
By looking into the detail, I found some weird things: No matter how many times dns.lookup (external API calls) happened, the dns.lookup took 10,000ms.
I tried to do the same load test to node.js applications running directly on linux servers, I didn’t see any obvious dns.lookup latency.
I didn’t get any clue from Google search results, hope I can get some insight and help here.
@docker4labs@iteamnetworkdc Has any of you found a resolution for this issue ?
I’m experiencing the exact issue with Node 6.2.0 running on Openshift Enterprise 3.
I can’t have every developer in our environment writing their apps like they did in the above link using Flask (moreover people don’t even think about it because they don’t know it at all)
