Test of gorouter performance in Cloudfoundry

I've always felt that the performance of Cloudfoundry's gorouter is not reliable, or that our Cloudfoundry deployment architecture is problematic, thinking about some stress tests, but has been plagued by tools that don't have stress testing. Last week, the department needed a test report, just to take this opportunity. Perform a better test.

When testing, is the use of the two Gorouter+nginx, testing the use of the application is a relatively simple application, using LoadRunner for stress testing, using LoadRunner 1000 users, the test results are very poor. and QQ Group of students to communicate, they also appeared similar problems, using F5 or haproxy are very normal, but the use of Nginx appeared many problems, performance is very poor. So also try to use Haproxy to do load balancing.

Haproxy deployment is not described, using the Haproxy default configuration, performance is also very poor, start tuning. Initially thought it was an application, a gorouter problem, but the positioning for a long time, found that these currently do not seem to have any problems. Finally, the configuration file for Haproxy is optimized and my Haproxy profile is:
