compare with python requests

[likezjuisee]

Why the latency result of the bom is different with the python requests package?

bom average 1.58ms, requests 250ms

bom result:

Well, I'm not all that familiar with python and requests library, but it seems like when you perform a single request, time to establish TCP connection, do a DNS lookup, etc. is much larger than the time to perform a single request (this is what you do with python). While with bombardier, by default, you establish something like 125 TCP connections, which are reused, and perform as many requests as you can in 10 seconds — 63013 in your case. With this setup, time to establish TCP connections (etc.) becomes negligible compared to the total time spent performing requests and therefore you get the results that you are seeing.
You should probably get something close to your python's results if you use bombardier -n 1 <url>.

I just noticed that you forgot to double-quote URL for bombardier, i.e. you type:

./bombardier-linux-amd64 -n 1 http://10.209.5.34:8013/hotrizon/get-score?m2=0000090ecb899d858576495c70f27a29&qid=123

, but it should be:

./bombardier-linux-amd64 -n 1 "http://10.209.5.34:8013/hotrizon/get-score?m2=0000090ecb899d858576495c70f27a29&qid=123"

Might not be the reason for the different results, but you test two different URLs.

Finally, I found this problem. Thanks!
