1 year ago Pressing a public service like baidu doesn't make any sense. The latency is too high, and there will be traffic controls. You should press a service in private net.
The parameters are also awful. Drogon uses nonblocking IO, 150 threads will not be faster than 8 threads (will be much slower in fact) if your machine does not have that many cores.
i want to use httpClient parts to do a lots of request .
i use the drogon-press-tool command: dg_ctl press -n 3000 -t 150 -c 3000 https://www.baidu.com
request 1000 times ,use 150 thread ,max to 3000 connections. it takes a long time and won't stop.
and i reduce the values .
try like below:
dg_ctl press -n 1000 -t 200 -c 100 https://www.baidu.com

and i wrote a test tool by c11-thread and curl .in the same machine and network. it can reach to 600 ~ 700 rps. only success. same target url.
i just loop 3000 request to 150 thread each request 20 at the same time .
how to reach the closely result as curl .
by the way .i use Locust . an other press tools it seems can reach the similar speed.
is there other setting limit the speed ?
other info :
use wrk tool:
