I am tring to explore how much scale of my application could reach.
I am building a very simple application which only has one rest api function.
First, I build the api login which will accept the user/password and compare them with the user stored in the database, then generate a key and return to user.
Basicly, this api has two operations
1.Read postgres db
2.Generate token and write to memory
I am using Jmeter to simulate 100 users concurrent access case.
Then I got the following result.
The average resp time is 37294ms and error rate is 34%.
And from the error log, this should caused by http timeout.
org.apache.http.NoHttpResponseException: 10.193.0.223:4001 failed to respond
My app depolyed with docker.
OS:Ubuntu 16.04.2 LTS, 8CPU and 16G Mem
I guess there will be some improvement about this.
My question is how could I find the bottle neck and imporve the overall throughput.
I want to know the limit of phoenix web application.
