Performance Test Report
Conclusion: on-line to meet the conditions, the volume of gray on the line and follow recommendations peak bandwidth consumption trend.
Testing process
Estimated sphere of influence:
On a custom template range estimating line properties affect mainly H5 template information renderer, a new interface views with reference to the H5 line PV, to be carried in single 700 + QPS
Test interfaces: an interface template information template-info
/service/article/template-info
Parameters content:
{"mask_id":"${article}"}
Select the article musk_id active users csv config file to cache
Return result mainly in two ways:
1, the article did not use a template that is no template article
2, the article uses the template, the server will return the template information
Body body found there may be a greater risk.
The first pressure measurement results analysis
QPS guess bottleneck in the article-6 exit insufficient bandwidth
Analysis of measurement results of the second pressure
Aritcl-6 modified the bandwidth of 20M, qps not rise
After the final positioning of the current exclusion QPS slb bottleneck that limits the number of connections
slb connections monitoring ⬇️
Slb line connecting the maximum number of 100,000 so this problem does not exist
The current number of connections can be via direct connection or modified gray slb article-6 machine circumvent this problem
In order to quickly verify the results quickly, article-6 attempts to access the network through a direct connection can be found in
[root@test-perf 5.4]# curl -X POST http://172.17.27.196:81/service/article/template-info -d '{"mask_id":"jogo4fc"}'{"code":1000,"err":false,"msg":null,"data":{}}
After modifying the third pressure measurement results analysis
Stand-alone QPS finally succeeded in rising to 1400 + security zone (peak single line network around 700QPS), but focus on other indicators found the problem:
1, as originally estimated risk, corresponding to peak when the QPS high bandwidth requirements, the bandwidth required to achieve single 130m, while net current machine configuration generally can not be achieved ⬇️
2, the test machine CPU consumes more than 90%
Body Analysis
Use template gripping articles returned from the server for analysis

amendment:
Image CDN instead issued, modified server response body:

After optimization of the fourth pressure measurement results analysis
QPS rise to 200 + 1600, reducing bandwidth by six times.
Basically meet the conditions on the line, but need to focus on the corresponding line and make adjustments during the bandwidth consumption peak.
